Hydraulic Quick Coupling (Steel)

ISO-7241-A, Poppet Valve, Pressure Eliminator On Male Side Only

This EH series is interchangeable with FASTER 3CFPV SERIES, PARKER RSD SERIES, DNP PPK3 SERIES, STAUFF UX SERIES, and VOSWINKEL UX SERIES. Steel Product. Designed for direct installation into valve ports or rigid piping systems, this coupling series meets stringent ISO 7241-1 Series A standards while incorporating critical safety features. The innovative breakaway function provides essential protection against equipment damage by automatically disconnecting the male coupling component when subjected to accidental tractor pull forces, effectively preventing hose rupture. This safety mechanism ensures operational reliability in demanding agricultural and industrial applications where unexpected tension may occur. Max Flow rate is 200 L/min.
