Series 320 coupling is an easy-to-handle high performing coupling with a long service life. It 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. The couplings have a smaller outside dimension than comparable designs. Full automatic operation ensures easy handling. It complies with ISO Standard 4414.

Series 320 is also available in Soft-Line, Multi-Link versions and in stainless steel version, Series 326.Series 320 coupling is an easy-to-handle high performing coupling with a long service life.
