Series 331 eSafe, DN 7

Series 331 eSafe couplings has high flow rate and low connection force. eSafe is a one hand operated safety coupling that vents before disconnection eliminating the risk of hose whip. Male threads on the couplings and nipples feature pre-applied thread sealant. A fully automatic operation ensures quick and easy handling. eSafe complies with ISO Standard 4414 and EN 983.
