Hatsan Vulnippel met Foster Koppeling – Quick-connect coupling for PCP airguns

This coupling piece from Ram Tactical simplifies the filling process of Hatsan PCP airguns. The component features a male Foster connector and silver finish, providing universal compatibility with most PCP filling systems equipped with female Foster connections.

Construction and materials

The coupling utilises standard Foster quick-connect technology with a male configuration. The brass construction includes O-ring seals that ensure an airtight connection during filling operations. The silver finish provides corrosion resistance while maintaining the durability required for repeated connections and disconnections.

Application and use

This coupling mounts directly onto the fill port of Hatsan PCP airguns. Once installed, users can quickly switch between different fill sources without tools. The component enables connection to hand pumps, dive bottle fill sets, and compressor systems equipped with female Foster fittings. The quick-connect mechanism allows attachment and detachment within seconds.

Integration and compatibility

The coupling is compatible with all standard Foster systems. The male connector fits female Foster connections commonly found on PCP filling equipment. This includes hand pumps, fill whips, and adapters used with dive bottles or compressors. The universal Foster standard ensures broad compatibility across different manufacturers' filling systems.

Maintenance and lifecycle

The O-ring seals require periodic inspection and may need replacement after extended use. Regular cleaning of the connector surfaces helps maintain proper sealing and prevents air leaks during filling operations.
