                                PROXY STATEMENT

                          ---------------------------

     This Proxy Statement and the form of proxy enclosed herewith, which are
first being mailed to stockholders on or about March 31, 1997, are furnished in
connection with the solicitation by the Board of Directors of Penn Engineering &
Manufacturing Corp. (the "Company") of proxies to be voted at the Annual Meeting
of Stockholders (the "Annual Meeting") to be held on Wednesday, April 30, 1997
at 2:00 p.m., local time, and at any adjournment, postponement or continuation
thereof, at the offices of the Company, Building #3, Old Easton Road, Danboro,
Pennsylvania 18916. The Company's principal executive offices are located at
Building #1, Old Easton Road, Danboro, Pennsylvania 18916.

     Shares represented by proxies in the accompanying form, if properly signed
and returned, will be voted in accordance with the specifications made thereon
by the stockholders. Any proxy not specifying to the contrary will be voted for
the election of the nominees for Class C Director named below and in favor of
the election of Deloitte & Touche LLP as auditors of the Company for its 1997
fiscal year. A stockholder who signs and returns a proxy in the accompanying
form may revoke it at any time before it is voted by giving written notice of
revocation or a duly executed proxy bearing a later date to the Secretary of the
Company or by attending the Annual Meeting and voting in person.

     The cost of solicitation of proxies in the accompanying form will be borne
by the Company, including expenses in connection with preparing and mailing this
Proxy Statement. Such solicitation will be made by mail and may also be made on
behalf of the Company by the Company's regular officers and employees, none of
whom will receive special compensation for such services. The Company, upon
request therefor, will reimburse brokers, nominees, fiduciaries and custodians
and persons holding shares in their names or in the names of nominees for their
reasonable expenses in sending proxies and proxy material to beneficial owners.

     The Company has two classes of common stock: Common Stock, par value $.01
per share ("Common Stock"), and Class A Common Stock, par value $.01 per share
(the "Class A Common Stock"). Holders of record of both classes at the close of
business on March 14, 1997 will be entitled to notice of the Annual Meeting, but
only holders of Class A Common Stock of record at the close of business on March
14, 1997 will be entitled to vote at the Annual Meeting. As of March 14, 1997,
the Company had outstanding 1,707,082 shares of Class A Common Stock, each of
which is entitled to one vote. Cumulative voting rights do not exist with
respect to the election of directors. The holders of Common Stock will have no
voting rights at the Annual Meeting. For purposes of the Annual Meeting, a
quorum means a majority of the outstanding shares of Class A Common Stock
represented in person or by proxy at the Annual Meeting.

     As of March 14, 1997, certain stockholders listed in the table herein under
"Beneficial Ownership of Common Stock and Class A Common Stock" beneficially
owned in the aggregate 894,890 shares, or approximately 52.4%, of the Company's
outstanding Class A Common Stock. Such stockholders have advised the Company
that they will vote their shares for the election of Willard S. Boothby, Jr.,
Thomas M. Hyndman, Jr., and Daryl L. Swanstrom as Class C Directors and for the
election of Deloitte & Touche LLP as the Company's auditors for 1997.
Accordingly, Messrs. Boothby and Hyndman and Mrs. Swanstrom will be elected as
Class C Directors, and Deloitte & Touche will be elected as auditors for the
Company for 1997 regardless of the votes of the Company's stockholders other
than those listed in such table.

                             ELECTION OF DIRECTORS

     At the Annual Meeting, three Class C Directors will be elected for a term
expiring at the 2000 Annual Meeting of Stockholders and when their successors
have been duly elected. The Class A Directors and the Class B Directors will
continue in office for the remainder of their respective terms shown below.
Under the Company's By-laws, the number of directors constituting the entire
Board of Directors is determined by the Board of Directors, but such number may
not be less than three nor more than twelve. The Board of Directors has
currently fixed the number of members of the Board of Directors at eight.

     Unless otherwise instructed, the proxy holders will vote the proxies
received by them for the election of the nominees for Class C Directors listed
below, each of whom is currently a director of the Company. If any nominee
becomes unavailable for any reason, it is intended that votes will be cast for a
substitute nominee designated by the Board of Directors. The Board of Directors
believes that the nominees named will be able to serve if elected. Any vacancy
on the Board of Directors for any reason may be filled by the affirmative vote
of 80% of the directors then in office. The three nominees for Class C Director
receiving the highest number of votes cast at the Annual Meeting will be
elected. Shares held by brokers or nominees as to which the broker or nominee
does not have discretionary voting power, i.e., broker non-votes, will be
treated as not present and not entitled to vote with respect to the election of
directors. Abstentions and broker non-votes on the election of the directors
will have no effect since they will not represent votes cast at the Annual
Meeting for the purpose of electing directors.

     Certain information with respect to each nominee for Class C Director, and
each Class A Director and Class B Director continuing in office following the
Annual Meeting is as follows:

(1) All shares underlying options are shares of Common Stock. Each option
    becomes exercisable in increments of 25% of the shares underlying such
    options commencing on the first, second, third and fourth anniversaries of
    the date of the option grant.

(2) The Black-Scholes model, a widely used and accepted formula for valuing
    traded stock options, was used to determine the grant date present value of
    the executive stock options. The Black-Scholes value used in this table is
    the same value used to report the expense associated with stock options in
    the Company's audited financial statements in accordance with FAS 123. The
    following assumptions were used to calculate the Black-Scholes value: a
    six-year option term, 30% stock price volatility, 5.93% risk-free rate of
    return, annual dividend yield of 2.25% and an exercise price equal to stock
    price on the date of grant. The Company has used the historical annual
    dividend yield and stock price volatility rate as assumptions for the
    Black-Scholes model. These are not projections, and therefore there is no
    guarantee that these assumptions will be the actual annual dividend yield or
    stock price volatility rate over the next six years. There is no gain to
    executives, however, if the per share market price of the Company's Common
    Stock does not increase or declines.

REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS

     The Company's executive compensation policies are intended to focus the
executive's attention and efforts on the attainment of Company goals, reward the
executive for the successful attainment of those goals, provide a total
compensation package that is competitive with the market for similar talent, and
create a feeling of shared destiny between the executives, all the other
employees and the Company's stockholders.

     Prior to the Company's fiscal year ended December 31, 1996, the
Compensation paid to the Company's executive officers, including its Chief
Executive Officer and the four other highest paid officers (the "Named Executive
Officers") consisted of a base salary and an annual bonus determined in
accordance with the provisions of a formal incentive plan (the "Executive Bonus
Plan") originally adopted for the year 1992 and amended thereafter from time to
time. The executive officers also are participants in the Company's profit
sharing plan, its pension plan, the 1996 Employee Stock Purchase Plan, the 1996
Equity Incentive Plan, and its various fringe benefit programs.

     In 1996, the Board of Directors and Stockholders adopted the 1996 Equity
Incentive Plan. The 1996 Equity Incentive Plan was approved by the stockholders
of the Company at their annual meeting in May 1996. The 1996 Equity Incentive
Plan covers all employees and officers of the Company, including the Named
Executive Officers.

     The 1996 Equity Incentive Plan provides for the grant of options to
purchase up to 500,000 shares of the Company's Common (Non-Voting) Stock at a
price not less than 100% of the fair market value of such stock on the date the
option is granted (except, in the case of an incentive stock option grant, if
the optionee owns more than 10% of the combined voting power of all classes of
stock of the Company, the option price must be at least 110% of the fair market
value of the stock on the date of grant). The 1996 Equity Incentive Plan is
administered by the Compensation Committee of the Board which has the authority
to determine the officers and employees to

                                       11
<PAGE>
whom options shall be granted and the type, amount, size, and terms of each such
grant (subject always to all of the requirements of the 1996 Equity Incentive
Plan). The purposes of the 1996 Equity Incentive Plan are to provide longer term
incentives to the officers and employees of the Company by enabling them to
participate in the growth in value of the capital stock of the Company and to
better align their long-term interests with those of the Company's stockholders.

     The annual salaries of the Named Executive Officers for fiscal year 1996
were determined in the month of December 1995. In determining the annual salary
for each of the executive officers of the Company, including the Named Executive
Officers, the Compensation Committee sought to establish salaries that were fair
and competitive with those paid by comparable organizations and that fairly
reward the executive officers for their performance and the Company's
performance. In determining the annual salary of each of the Named Executive
Officers, other than the Chief Executive Officer, the evaluation of the Chief
Executive Officer of their performance is considered, and each position is
measured against the knowledge and problem-solving ability required to fulfill
the assigned duties and responsibilities of such position and the officer's
impact upon the operations and profitability of the Company.

     The same considerations were taken into account in fixing the Chief
Executive Officer's salary for 1996, except that the Committee did not have the
recommendation of the Chief Executive Officer.

     The salary increases of the Named Executive Officers, other than the Chief
Executive Officer, for 1996 approximated 4%. The Chief Executive Officer's
salary increase for 1996 was approximately 3.7%.

     Payments to the Named Executive Officers under the Executive Bonus Plan are
determined by five factors, which combined are used to determine the amount of
the annual bonus. The first and second factors, each with a weighting factor of
25%, compared the Company's 1996 net income with 1995 net income and the 1996
Business Plan net income. The third and fourth factors, each with a weighting
factor of 10%, compared the Company's 1996 consolidated net sales with 1995
consolidated net sales and the 1996 Business Plan consolidated net sales. The
fifth factor, with a weighting factor of 30%, compared 1996 return on equity, as
defined in the 1996 Business Plan, with 1995 return on equity. The target bonus
for each officer, other than the Chief Executive Officer, the Treasurer, and the
Corporate Controller, is 25% of the individual's base salary. The target bonus
for the Chief Executive Officer is 40% of base salary, and for the Treasurer,
and Corporate Controller, is 20% of base salary. The relationship of the
Company's 1996 results for each factor to the prior year or the 1996 Business
Plan, as approved by the Board of Directors, can cause the annual bonus to range
from zero to 150% of the targeted amount. The consideration of earnings before
interest and taxes is the most significant factor in determining the annual
bonuses paid to all other salaried and hourly workers under the employee
incentive plan. Consolidated net income is the most significant factor in
determining the annual bonuses paid to the executive officers. These two
measures of earnings extend a common thread in the standard of measure for both
executive officers' and other employees' annual bonuses.

     Both the fastener and motor operations failed to meet the overall targets
established by the Board of Directors for 1996, and, therefore, the bonuses
under the incentive plans were less than the targeted awards for all
participants.

     The bonus paid to the Chief Executive Officer for the year 1996 was
determined in accordance with the current provisions of the Executive Bonus Plan
and reflects, in the opinion of the Committee, appropriate rewards for the
Company's current performance. The portion of the Chief Executive Officer's
bonus as compared to his 1996 target bonus for each factor was as follows: 1996
net income as compared to 1995 net income was 100.42% of target; 1996 net income
as compared to the 1996 Business Plan net income was 84.34% of target; 1996 net
sales as compared to 1995 net sales were 113.48% of target; 1996 net sales as
compared to the 1996 Business

                                       12
<PAGE>
Plan net sales were 96.42% of target and 1996 return on equity as compared to
1995 return on equity was 86.09% of target. Therefore, the total bonus paid to
the Chief Executive Officer for 1996 was $104,142. This bonus was $7,858 or
7.02% less than the target amount.

     In determining the grants of stock options under the 1996 Equity Incentive
Plan, the Compensation Committee took into account the various factors
(described above) considered in determining the annual salaries of the Named
Executive Officers, as well as the recommendations of the independent consultant
which assisted in the creation of the Plan. In 1996, the Chief Executive Officer
was granted non-qualified options to purchase up to 15,000 shares of the
Company's Non-Voting Common Stock and each of the other Named Executive Officers
was granted non-qualified options to purchase up to 10,000 shares of the
Company's Non-Voting Common Stock.

     Section 162(m) of the Internal Revenue Code generally disallows a tax
deduction to a public company for compensation over $1 million paid to each of
the company's chief executive officer and the four other most highly compensated
executive officers. Qualifying performance-based compensation will not be
subject to the deduction limit if certain requirements are met. The Committee
did not consider the deductibility for federal tax purposes of the compensation
paid to the Chief Executive Officer and the Named Executive Officers under the
provisions of Section 162(m) given their current compensation levels. The
Committee intends to take the necessary steps to conform the Company's policies
with respect to executive compensation in order to comply with the provisions of
Section 162(m) if and at such time as the deductibility thereof becomes affected
by such provisions.

                                          Respectfully submitted by
                                          the Compensation Committee
                                          of the Board of Directors

(1) The comparisons of total return on investment (change in year-end stock
    price plus reinvested dividends) for each of the periods assumes that $100
    was invested on December 31, 1991 in each of the Company's Common Stock, the
    S&P 600(Registered) SmallCap Index, the AMEX Market Value Index, and the S&P
    Indices with the investment weighted on the basis of market capitalization.
    Inasmuch as the Company has listed its Common Stock and Class A Common Stock
    on the New York Stock Exchange, the Company has added the S&P
    600(Registered) SmallCap Index to this performance graph, and the Company
    does not intend to include the AMEX Market Value Index in future years.

     Credited full years of service for the five officers listed in the Summary
Compensation Table are as follows: Kenneth A. Swanstrom, 36 years; Mark W.
Simon, 20 years; Martin Bidart, 6 years; Raymond L. Bievenour,
6 years; and Richard B. Ernest, 35 years. The covered compensation under the
Pension Plan Table is that amount shown in the salary and bonus columns of the
Summary Compensation Table. The amounts shown in the Pension Plan Table do not
reflect any deduction for social security or other offset amounts. Benefits are
subject to maximum limitations under the Internal Revenue Code of 1986, as
amended (the "Code"). Therefore, with regard to 1996, the maximum salary that
can be recognized under the plan is $150,000 and the maximum annual benefit at
age 65 is limited to $120,000. The foregoing Pension Plan Table may be used for
all five officers, except for Kenneth A. Swanstrom, who is entitled to a higher
benefit due to plan provisions protecting prior accrued benefits. Mr.
Swanstrom's projected annual benefit at age 65, after 44 years of service, is
$107,479.

of $250 for each meeting attended in 1996. Members of the Audit Committee and
the Compensation Committee each receive a fee of $500 for each meeting attended

were required for those persons, the Company believes that, during the period
January 1, 1996 through December 31, 1996, all filing requirements applicable to
its officers and directors were complied with, except that Lewis Hull filed an
amended Form 5 late to report the transaction by his wife for the purchase of

acquisition of 25 shares of Common Stock by his daughter on his Form 5 report.
