In 1955, Carl Erik Josef Nyberg (CEJN) 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. CEJN’s design is based on small external and large internal dimensions. Ever since CEJN invented and patented the first coupling, they have been expanding their product lines, from compressed air initially to now include and cover media such as breathing air, hydraulic oil and fluids. From quick disconnects to gauges and hoses, CEJN has everything you need for your turn-key ultra-high pressure system.
