In 1955, Carl Erik Josef Nyberg (C.E.J.N.) designed and patented a revolutionary quick connect coupling that overcame many of the shortcomings of previous designs. It dramatically simplified handling and provided reliable, efficient connections.
CEJN's Pneumatic product line includes the world’s best-performing quick connect couplings, blowguns, polyurethane hoses, lightweight and heavy-duty hoses, cable reels and accessories. CEJN offers all the necessary components, from FRL units to compressed air couplings, to ensure reliable compressed air performance worldwide. See all products ->
Breathing Air Products
CEJN Breathing Air couplings have a high-flow rate, a broad connection range and require only minimal force to connect. With the vital function of supplying breathing air, the need for safety and reliability is of the utmost importance. CEJN's products are designed and manufactured to exacting standards, which has resulted in years of trouble-free service. Presented here are CEJN’s couplings and nipples, hoses, hose kits and accessories for breathing air applications.
Ultra High-Pressure Hydraulic Products
CEJN has over 40 years of experience in quick connect coupling technology for high-pressure hydraulics and offers a wide range of products with operating pressures up to 3000 bar (43,500 PSI), CEJN High-Pressure Hydraulic couplings are specially designed for ultra high pressure pumps, rescue equipment and other demanding applications. See all products ->
Thermal Control Products
For temperature control and thermal management, we offer a range of standard and specially-designed couplings and nipples. At the heart of electronic systems, where just a drop or two might be sufficient to cause damage, CEJN offers a blind-mate coupling and nipple with a non-spill feature that guarantees high-flow and spill-free operation. CEJN'’s Non-Drip series is another solution. This is a flat-face valved quick disconnect coupling series with dry-break function for data servers, power electronics and other cooling applications.

To quickly connect and disconnect are abilities products for fluids must have, as well as being leak free, able to withstand the media transferred and to endure the operating conditions they are subjected to. All of which CEJN Fluid products have. Couplings and nipples for fluids are available in valved and valveless designs for low- and medium pressure application. Presented here are couplings and nipples, hoses and hose kits for fluid applications.
CEJN Hydraulic couplings are suitable for applications with operating pressures reaching up to 700 bar (10153 PSI). By using CEJN Hydraulic couplings, pollution through hydraulic fluid leakage is reduced and helps to protect the environment from harm. Presented here are couplings, nipples, and pressure testing systems for all types of hydraulic applications. See all products ->
MULTI & AUTO Products
CEJN’s Multi- & Auto products are high-tech couplings and nipples designed to be built into manifolds and plates. This enables several fluid lines to be engaged and connected and disconnected in an instant. Presented here are three styles designed for modular systems: Automation couplings suitable for fluid or hydraulic applications and the Multi-Snap system for fluid applications. See all products ->
CEJN’s Gas product line meets the extra stringent safety demands of gas applications. The products have an automatic safety-locking feature and double seal functions for extra safety protection, plus colour coding on both the couplings and nipples. Presented here are CEJN’s couplings and nipples for gas applications.
