CEJN® Series 310 Couplings - Industrial Ancillaries

CEJN® Series 310 eSafe Couplings

  • CEJN Series 310 offers a wide range of easy-to-grip couplings, including Soft-Line, Stream-Line, and Multi-Link couplings. Male threads on the couplings and nipples feature pre-applied thread sealant. The Series 310 vented safety version is disconnected in two stages in order to vent the coupling and minimize the risk of sudden component separation, which has the potential to cause operator injury. Full automatic operation ensures easy handling. The vented safety version complies with ISO Standard 4414 and EN 983.
