Quick Connect Coupling ARS178L Stainless – 1/2" BSP Female – PA

The PA ARS178L is a 17.8 mm stainless steel ball-type quick connect for high-flow cleaning systems. The larger 12 mm bore keeps pressure loss low on 1/2" lines, and the stainless body with Viton seals suits hot water and chemical use.

This is the coupling (female quick-connect) half with a 1/2" BSP female thread, normally fitted to the hose or pump end.
