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 founder Carl, who struggled to keep up with his hourly piece-work as a tool grinder at the Royal Armour Regiment. Right from birth Carl had the mind of an inventor and he set out to invent a new, improved coupling. This new product became the basis for a large part of CEJN’s modern range of products as well as the starting point for their global growth.
Their design is based on small external and large internal dimensions. Ever since Carl invented that first coupling, patented in 1955, CEJN have been expanding their product lines, from compressed air initially to now include and cover media such as breathing air, hydraulic oil and fluids. They concentrate on developing innovative engineering solutions with a focus on safety as well as continuing to improve standard products and designing new ones.
