Foster Male Quick Coupling – 1/8 BSP adapter for HPA and PCP systems

This Foster Male quick coupling from RAM Tactical is a stainless steel adapter that connects filling nipples to Foster Female couplings. With its 1/8 BSP female thread, this coupling fits all connections with 1/8 BSP male thread, making it versatile for both PCP air rifles and HPA airsoft systems where Foster couplings are standard.

Construction and materials

The Foster Male coupling is manufactured from stainless steel and includes a sealing ring for an airtight connection. The silver finish provides corrosion resistance suitable for compressed air applications. The integrated valve mechanism automatically seals when disconnected, preventing pressure loss and maintaining system integrity.

Application and use

This coupling serves as a connection point between filling systems and air weapons or HPA tanks. The adapter screws onto components with 1/8 BSP male thread such as regulator outputs, filling stations, or direct tank connections. Once mounted, you have a Foster Male connection ready for Foster Female filling hoses.

Integration and compatibility

The coupling features 1/8" BSP thread, a common size in compressed air applications. Compatible with most regulators, filling stations, and compressed air accessories. The included sealing ring ensures leak-free mounting without requiring additional thread tape. Works with both PCP and HPA systems using Foster-type connections.

Maintenance and lifecycle

The stainless steel construction requires minimal maintenance. Periodically check the sealing ring for wear and replace if necessary to maintain airtight connections. The coupling is fully serviceable with replacement O-rings available.
