About CEJN

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.

Following World War II, compressed air was increasingly used as an energy source for pneumatic tools and equipment. Leaking and inefficient couplings were a common problem, and one also experienced by our founder Carl, who struggled to keep up with his hourly piece-work as a tool grinder at the Royal Armour Regiment. This new product became the basis for a large part of CEJN’s modern range of products as well as the starting point for our global growth.

Our design is based on small external and large internal dimensions. At CEJN, we are united by our five core values: safety, environment, quality, innovation and performance. They are our cornerstones and define who we are, how we work, what we believe in and what we stand for.
