55 Series 

Hydraulic Full Flow Pressure Washer Unvalved Coupling (Brass, AISI 316 Stainless Steel)

This EH series is interchangeable with HOLMBURY PWS SERIES. This series is full flow without valve couplings for applications where maximum flow is required. Its smooth, open bore offers the lowest pressure drop of any quick coupling design. It is ideal for applications such as high-pressure water and steam washers, carpet cleaners, and mold coolant lines, and the transmission of non-hazardous fluids.
