Foster Male Quick Coupler – Adapter for your HPA or PCP setup

This Foster Male quick coupler from RAM Tactical is a stainless steel adapter that simplifies connecting fill nipples to Foster Female couplings. With its 1/8 BSP female thread, this connector fits all connections with 1/8 BSP male thread, making it widely applicable for both PCP air rifles and HPA airsoft systems where Foster couplings are the standard.

Technology and application

The Foster Male coupling is made from stainless steel and equipped with a sealing ring for an airtight connection. The Foster system is known for its fast and reliable coupling mechanism – you push the Female side in and the connection is made. When disconnecting, the valve automatically closes, preventing pressure loss. The 1/8" BSP thread is a commonly used size in compressed air applications, making this adapter compatible with many regulators, fill stations, and compressed air accessories.

Ease of use and integration

This connector functions as a connection point between your filling system and your airgun or HPA tank. You screw the adapter onto a component with 1/8 BSP male thread – think of a regulator output, fill station, or direct tank connection. Once installed, you have a Foster Male connection where you can directly attach Foster Female fill hoses. The included sealing ring ensures a leak-free installation without the need for additional Teflon tape.

Who is this connector intended for?

This adapter is ideal for PCP shooters who fill their air rifle from a diving cylinder or compressor with Foster couplings. Airsofters with HPA replicas who fill their tanks via Foster connections will also benefit from this component. Technicians looking to create multiple filling points in their workshop or users seeking spare parts for their existing fill set will find a reliable solution here.
