Series 320 couplings feature the original high-flow valve design upon which all other CEJN pneumatic
couplings are based. Their popularity has made Series 320 a European standard. The Series is easy-tohandle and one-hand operated and offers long service life. Male threads on the couplings and nipples
feature pre-applied thread sealant. Lightweight aluminum styles are also available. The Series 320 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
