Ultra High-Pressure Hydraulic Products

Couplings & Nipples

CEJN High-Pressure Hydraulic couplings and nipples are depended upon throughout the world to help keep ships sailing, wind turbines turning, subsea exploration equipment drilling and a whole lot more high/ultra pressure hydraulic applications. They are based on a CEJN original design that has grown into a global standard. That's proof that we've always been one step ahead and we continue to be with 40 years of experience in everything we do. All CEJN High-Pressure Hydraulic couplings and nipples are designed with a non-drip interface to minimize fluid spillage and air inclusion during connection and disconnection. Dust caps are a standard feature to protect hydraulic systems from contaminants.
