Holmbury Screw To Connect and Pressure Washer Couplings

Screw to Connect Couplings – TC Series

Description Holmbury’s TC Series screw to connect tipper couplings are designed for use on tipper trucks. The female coupling has a wing nut sleeve which enables operators to connect the couplings by hand, even when there is low residual pressure in the line.

Features • Screw connect design eliminates brinelling • Wing nut sleeve design allows connection by hand • Can be connected with up to 50 bar residual pressure in the hydraulic circuit • Bi-directional flow • Male has external thread for bulkhead mounting

Pressure Washer Couplings – PWC Series

Description Holmbury’s PWC Series couplings are able to accommodate high flow rates and minimal pressure drops. The couplings are valveless, hence when disconnected, any fluid in the system can escape. This makes these couplings suitable for the transmission of non-hazardous fluids only.

Features • Valveless design allows for high flow rates and minimal pressure drop characteristics • Female half has double O-ring sealing arrangement • Bi-directional flow
