About CEJN

CEJN is a third-generation Swedish family-owned company that develops and manufactures high-performance quick couplings and related products such as hose and cable reels, hoses, multi-couplings and tank fittings. The company was founded in 1955 by Carl Erik Josef Nyberg, who designed and patented a revolutionary quick coupling that replaced unreliable, leaky connections on compressed air tools. Today the portfolio includes more than 9000 active products for pneumatics, medium- and high-pressure hydraulics as well as fluid and breathing air applications. In addition to the standard range, CEJN develops custom solutions: every project is supported by a dedicated Design Engineer and Application Expert, from prototypes and small series made of special materials to complete Auto Dock Systems (ADS). Customers include companies such as Arden Equipment, Ullmann, Epiroc and MSM. The company operates 19 sales offices and 4 production sites worldwide; production is powered entirely by renewable energy.
