CEJN Full-Flow Couplings

New CEJN Full-Flow Couplings
Offer Unrestricted Flow
CEJN’s new full-flow couplings, for low-pressure fluid applications,feature a valveless design that permits unrestricted, high flow.
When customers approached CEJN for a coupling that would offer maximum fluid
flow, CEJN engineers asked just what would satisfy their needs. They heard requirements such as:• No flow restrictions• Uncomplicated, compact design• Easy to maintain and service• Tarnish-resistant finish• EconomicalPutting to work the strengths behind its Global Quick Connect Specialist reputation,
CEJN transformed the requirement list into new full-flow couplings for fluid applications.

Economical Valveless Design
CEJN full-flow couplings feature an economical valveless design that permits unrestricted, high flow and accommodates high viscosity fluids. The straightforward design
reduces pressure drop.
Engineered with the high quality that customers expect with couplings bearing theCEJN name, the new quick-connect couplings offer long service life in low-pressure
applications, such as fluid transfer, mold coolant/heating, chemical processing, andvacuum service.
Connections are made by simply pulling back the locking sleeve with one hand andpushing in the nipple with the other hand. The couplings are easily wiped clean, andthe internal O-ring is easy to access and replace.
The new couplings are available in high-gloss, nickel-plated brass and electro-polished
AISI 316 stainless steel in flow diameters: 25 mm (1”), 38 mm (1½”), and 51 mm (2”).

Safety Options
CEJN full-flow couplings are offered with optional color-coded rings that can be used
to identify media and/or pressure lines and the corresponding nipple for each coupling.
Color-coded rings are available in green, red, black, blue, yellow, and white and withstand temperatures up to +125°C (+250°F).
An optional safety-locking device eliminates the risk of unintentional disconnection.
When the nipple is connected and locked into place, the locking feature engages bymanually turning the locking sleeve. Disconnection is achieved by turning the locking
sleeve back into position. The nipple can only be disconnected when the locking sleeve
is in the correct position.
