About CEJN
CEJN is a Swedish manufacturer of high-performance quick-release coupling solutions for pneumatics, medium- and high-pressure hydraulics and fluid technology. Founded in 1955 by Carl Erik Josef Nyberg and managed by the third generation, the family-owned company manufactures quick couplings, hose and cable reels, hoses and hose assemblies, air and fluid guns, hydraulic pumps as well as maintenance units and offers custom solutions from prototypes to small series. The value chain includes development and design, machining of components (including brass, steel), surface treatment, assembly and pressure testing; hoses are made of polyurethane (PUR) or rubber (EPDM) and pre-assembled hose lines are offered from Germany. Customer industries include construction machinery, wind power, data centers, electromobility, rail and aviation, fire and rescue services, shipping, agricultural and commercial vehicle technology as well as food production. Headquarters and production are located in Skövde (Sweden), with additional production and sales sites in Lönsboda, Troisdorf (Germany) and Shanghai (China); the company operates 19 sales offices worldwide.
