CEJN Nordic Range 525 are somewhat of a "Nordic standard" in steel. Its heavy-duty design ensures maximum durability and high performance. The products are equipped with additional security locking and extra sealing for improved performance. The optional pressure eliminator facilitates a low connection force even when either half is under residual pressure. The couplings and nipples are made of plated steel and those parts exposed to extreme strain and stress are hardened for extra durability. The Series is offered in five sizes ranging from DN 6.3 to DN 25.
