CEJN Quick Couplings & Cross-Reference

CEJN AB is a Swedish manufacturer of quick-disconnect couplings and nipples, founded in 1955 in Skövde, Sweden, where it remains headquartered and active. Its range spans pneumatic, hydraulic, breathing-air, and fluid-transfer connectors, with pressures from roughly 230 psi (16 bar) on the pneumatic side up to ultra high-pressure hydraulic couplings rated to 4,000 bar (400 MPa). Northern Hydraulics does not carry the CEJN catalog directly; instead we cross-reference CEJN quick couplers and nipples to equivalent coupler series, so send a model number for a replacement quote.

Cross-Referencing CEJN Parts

Most CEJN requests come down to one thing: an existing connector that needs a working equivalent. CEJN hydraulic couplings are built to ISO 16028 (flat-face), and the pneumatic lines follow common European profile standards, so many models cross-reference cleanly to interchangeable coupler series we already carry. Send the CEJN model or part number, the series family (for example a Series 310 or 320 pneumatic coupling, or an X-series flat-face hydraulic coupling), and the port thread, and we will match it to an equivalent quick coupler or nipple by connection profile, pressure rating, and flow size.

CEJN keeps an internal "Old Part Numbers" database for discontinued products, but that mapping is not publicly accessible, which is exactly why a cross-reference saves time on obsolete CEJN couplings. If you have a legacy Series 14 design or any superseded part number, we work back from the physical connection profile and pressure class to a current replacement. Request a CEJN cross-reference quote with your model number and we will return an equivalent.

CEJN Product Lines & Series

CEJN organizes its couplings into defined series families. The ones we cross-reference most often include:

• Series 310 / 320 — pneumatic quick couplings, with Series 320 following the European profile standard
• Series 340 — breathing-air couplings
• Series 430 / 550 eSafe — pneumatic safety and multi couplings with the eSafe venting feature
• Series 208 and 208 Detect — blowguns
• X-series (X62 / X64 / X65) — hydraulic flat-face couplings to ISO 16028
• Multi-X and TLX — hydraulic multi-plate and auto / multi coupling systems
• UHP (Ultra High-Pressure) — couplings and hoses for 3,000–4,000 bar service
• ultraFLOW — liquid cooling connectors
• Series 14 — the original 1955 patent design, now legacy

If your CEJN part falls in any of these families, include the series and size when you send it over so we can match the connection profile and pressure class precisely.
