Engineering Data

When PTFE* was developed in 1938, its importance to industrial sealing was quickly recognized because of its tremendous chemical resistance. While useof PTFE as a gasket material increased in industrial
applications, complaints about certain properties
started to build: skive marks made initial sealing difficult, cold flow caused leakage and premature failure,
and temperature/pressure cycling was a problem.

Resistance to Cold Flow (Creep)
These drawbacks were eliminated when Garlock
introduced Fawn GYLON®, Style 3500, in 1967. The
GYLON® process minimizes creep and cold flow normally associated with PTFE products, while retaining
other positive characteristics of PTFE. Fawn GYLON®
was so innovative that it received Chemical Processing
magazine’s Vaaler Award in 1968. As the variety andquantity of industrial chemicals increased, Garlock
realized that new products would be required to serve
the growing market. Two additional GYLON® styles wereintroduced to meet those demands: Blue GYLON®,
Style 3504, and Off-White GYLON®, Style 3510.

As the diversity of applications grew, so did thetypes of piping systems. A large number of exotic piping
systems was required to handle the many hazardousand corrosive chemicals on the market. A common
drawback of these types of piping materials is the small
amount of gasket load available before the flange isdistorted or cracked. In 1989, Garlock responded to thisproblem by introducing ENVELON®, another member of
the GYLON® family. ENVELON® has a soft material on
the gasket / flange interface where compressibility isimportant, but has a harder core in the middle to prevent media permeation and blowout.

High Pressure Service, Chemical Compatibility
As production demands increased, pipe hammering
and/or pressure spikes became more common.
GYLON® Series HP 3560 and HP 3561 were designed
to meet those extreme conditions. These perforated
stainless steel-inserted GYLON® gasket materials
outperform any other gasketing available for high pressure service where chemical compatibility is a concern.
* PTFE – polytetrafluoroethyleneiLow Bolt Load Sealing

Unparalleled Reliability and Service®

In 1994, Garlock introduced GYLON Style 3545 forlow bolt load applications. It is designed especially toseal pitted, warped or wavy flanges and many nonmetallic flanges. Featuring soft, compressible outerlayers and a rigid PTFE inner core, Style 3545 is ideal
in situations where a rigid gasket is required, such as
hard-to-reach piping systems, valves and flanges. The
layers of rigid PTFE and microcellular PTFE are
sandwiched together using the proprietary GYLON®
process, rather than adhesives, for longer gasket life.
Style 3545 is so innovative, it received the 1995 Vaaler
award from Chemical Processing magazine.

Unlimited Sizes and Dimensions
With growing concern over fugitive emissions, thetraditional dovetailing method of creating larger sizedgaskets no longer meets customer demands. In response, Garlock created the Welded GYLON® process.
Welded GYLON® eliminates dovetail leak paths andallows the use of large gaskets without handling problems or premature blowout. Today, GYLON® gaskets
can be welded to any size or dimension… anotherbreakthrough for Garlock gasketing!

The Garlock family of GYLON® products has
evolved over the years with a focus on quality to meetand exceed customer expectations. The use of
Employee Involvement, Statistical Process Control,
Vendor Assurance Programs, and a continuous
improvement philosophy guarantees end users thehighest quality products available.
Testing is performed regularly on all styles andthicknesses to ensure the consistency of Garlock quality in GYLON® sheets. Quality American-made products, 34 years of experience, on-time delivery andvalue-added service programs, all are reasons why the
GYLON® family of products has become such a major
sealing component in industry today.
There is no doubt that demands will change in the
future. But one thing is certain—Garlock will continue toanswer those changes and demands with products thatare innovative and timely. GYLON®, a name you cantrust and a complete family of products to choose fromfor your gasketing needs.

Gasket Installation"M" and "Y" Data

• Center the gasket on the flange. This is extremely
vital where raised faces are involved.
Note: Standard ANSI ring gaskets, when properly
cut, should center themselves when the bolts are inplace.

"M" and "Y" data are to be used for flange designs
only as specified in the ASME Boiler and Pressure
Vessel Code Division 1, Section VIII, Appendix 2. They
are not meant to be used as gasket seating stressvalues in actual service. Our bolt torque tables give that
information and should be used as such.

• Use a torque wrench and well-lubricated fasteners
with hardened flat washers to ensure correct initialloading.

"M" - Maintenance Factor• Tighten bolts to compress gasket uniformly. Thismeans going from side to side around the joint in astar-like crossing pattern. See Figure 3 below.
• All bolts should be tightened in one-third increments, according to proper bolting patterns.

A factor that provides the additional preload
needed in the flange fasteners to maintain the compressive load on a gasket after internal pressure isapplied to a joint. The net operating stress on a pressurized gasket should be at least (m) x (design pressure, psi).

"Y" - Minimum Design Seating Stress• Retorque 12 to 24 hours after start-up, wheneverpossible. All applicable safety standards including
lockout/tagout procedure should be observed.

The minimum compressive stress in pounds per
square inch (or bar) on the contact area of the gasket
that is required to provide a seal at an internal pressureof 2 psig (0.14 bar).

• Never use liquid or metallic based anti-stick or
lubricating compounds on the gaskets. Premature
failure could occur as a result.
