When customers all over the world need fluid systems to function without
failure, they turn to CEJN for innovative, problem-solving products. CEJN’s
reputation as a leader in fluid system components began over five decades
ago when the company pioneered compressed air couplings at a fledgling
assembly plant in Skövde, Sweden.
Today, that venerable facility stands as the international headquarters for CEJN, which now encompasses sales operations on four continents in 21 countries. The CEJN product line has evolved intoa wide range of quick coupling styles that are quickly chosen for applications involving not only thetransfer of compressed air, but also hydraulic oils, fluids, gases, and more. Also included in the CEJN
product line are accessory products, such as adapters, fittings, hose, hose reels, air-preparation units,
and blowguns.
Product Modifications, All-New Designs
The company’s hard-working commitment to developing new products also includes:• Modifying existing products when higher performance standards are required – and “off-the-shelf”
components won’t do. By continually investing in new processes and technologies, CEJN has the capability to modify products that exceed their original performance parameters and customer expectations.
• Designing and manufacturing limited quantities of custom couplings that are needed by customers
to replace troublesome products or build into new or existing applications. CEJN provides complete
product solutions from design to installation-ready components that are qualified, tested, and backed byafter-sale support.
Whether it’s a special coupling requirement for material construction, temperature range, end connection, or flow rate, CEJN engineers analyze each requirement and determine whether to build it into an
existing product or an all-new design.
Pioneering Spirit Leads to WEO Plug-In Hose Fittings
In fact, this pioneering spirit has led to CEJN’s entry in the threadless connector market with the development of WEO Plug-In hose fittings – CEJN’s response to customer inquiries for end connections that
simply “plug in” to hydraulic systems. The innovative click-to-connect feature of WEO fittings eliminates
the need for tools or wrenches that are needed to connect and disconnect traditional threaded fittings.
WEO fittings are leak-free and slash downtime for assembly and field maintenance, since only acommon screwdriver is needed to remove hose assemblies.
As more and more applications industry-wide are being converted from threaded to threadless connectors, WEO Plug-In hose fittings are becoming the connection of choice by well-known original equipment manufacturers for critical equipment applications.
Backed by extensive laboratory and field-testing, WEO fittings, offered with numerous connection
options, are being used by leading companies that supply products all over the world.

ISO 9001 certified since 1995.
ISO 14001 certified since 2006.

Partnering with Hose Manufacturers
In fact, because of the industry’s acceptance of CEJN threadless fittings, several international hose
manufacturers have partnered with CEJN in offering their customers hose assemblies equipped with
CEJN WEO products. These assemblies are of high interest to customers that are looking for a reliable,
proven threadless design that is backed by a premier hose manufacturer.
As a result, more and more global customers are “plugging in” to hydraulic systems without tools or
wrenches by specifying problem-solving WEO Plug-In hose fittings from CEJN, your quick connect
specialist.

Brokk Makes Buildings Come
Tumbling Down with Aid of
WEO Products“Getting in and out of job sites on time in order not to
disrupt critical time schedules and budgets is very
important to us. Therefore, it is crucial that Brokk
remote-controlled demolition robots are equipped withcomponents that are quick and easy to repair.
“For this reason, Brokk AB has supplied WEO Plug-In hosefittings on hydraulic oil lines on a robot being used for sortingand demolition in a nuclear waste station.

Contact person:

Anders Norberg, Design Manager
Company:

Brokk AB, Skellefteå, Sweden
www.brokk.com“The product has appealed to us because it is so quick and easy to install andmakes replacing hose assemblies almost effortless.
“At job sites, such as nuclear waste stations in which it can be extremely
tough to make hose assembly replacements due to the dangerous working
environment, WEO products may be just the solution we need.”

Rottne Logging Equipment
Clears the Way for WEO Fittings“Rottne logging cranes have very compact designs, which do
not offer a lot of clearance area for installing and repairing hoseassemblies with traditional threaded fittings and working with therequired hand tools.

WEO Products Are a Natural
Fit at Kanglim“CEJN’s WEO Plug-In fittings are a handy product for us because
they are quick and easy to connect and disconnect without
wrenches.

“Here at Kanglim, we place a major emphasis on using only state-ofthe-art hydraulic technology in our production of truck-mounted cranes
and special-purpose vehicles. This kind of commitment to innovation
makes WEO Plug-In hose fittings a natural fit at our assembly facility in
Chungcheongbuk-do, Korea.
“WEO fittings are used on high-pressure oil lines on the rotating arms of Kanglim
auger cranes. The self-alignment of WEO fittings allows the connecting hose to movefreely during installation, which has eliminated the problems of twisted hose andresultant shortened hose life.
“The use of threadless WEO fittings also has enabled us to reduce assembly time
for the auger cranes, since the fittings require only a quick ‘click’ to connect anddisconnect them.
“Because of the important, problem-solving benefits of WEO products, I would nothesitate to recommend them to other companies with similar applications.”

10“Here at our assembly facility in Rottne, Sweden, we use them on
hydraulic lines on the cranes’ extension cylinders.

Contact person:

Chan Ho Kim

Company:

Kanglim Company, Ltd.
Chungcheongbuk-do, Korea
www.kanglim.com“In the past, we have found that with screw-in fittings, it is impossible
to replace these hydraulic lines without completely dismounting thecylinders.
“With WEO fittings, downtime for field maintenance is minimal, since
only a screwdriver is needed to remove the assemblies, and replacements
just click into place.
“We have been using WEO products for the past five years and have had no
problems with their installation or performance.”

WEO Products Are Earth
Moving at Komatsu

Product Range“For the past two years, we have been using WEO connectors tojoin hose assemblies to servo controls on our Komatsu
earth moving equipment. These threadlessconnectors appealed to us because of the
difficulty we experienced in installing threaded
connectors in confined areas.
“WEO connectors are easy to install and also
provide easy maintenance and reliable sealing.
Since we build hundreds of machines eachmonth that require literally thousands of hoseassemblies, these are important benefits to us.

Contact person:

Gianni Contato, Supplier Auditor –Quality Assurance Department
Company:

Komatsu Utility Europe, Este, Italy
www.komatsu.it“We purchase the WEO-equipped hose assemblies
from a hose manufacturer that, along with CEJN, provides valuable
technical assistance. WEO’s reliable performance and its support
from two companies give us confidence in the product.”WEO Products Give
Palfinger Cranes a Lift
“The fact that threadless connectors do not require a lotof space for installation is what led us to try them on ourloading cranes.
“The hydraulic control valves on Palfinger cranes havenumerous hose connections, but are located in an areawith virtually no space for hand tools that are required
for making threaded connections.
“With our knowledge of threadless connectors, we
decided to try CEJN WEO Plug-In hose fittings on
the valve banks. After determining what fitting heat
treatment processes would and wouldn’t work for us, weare pleased with WEO’s performance.

Contact person:“Installing hose assemblies is no longer a problem at our assembly facility here
in Salzburg, Austria, or on the job site when hose replacements are needed.

Reinhard Sunkler, Purchasing –Hydraulic Parts Procurement“I would highly recommend WEO products to other manufacturers that have
limited access space on their equipment. WEO fittings that automatically lock
into place have been the answer for us.”Palfinger AG, Salzburg, Austria
