Hatsan Quick-Connect Fill Nipple – Foster male coupling for PCP airguns

This fill nipple provides a direct connection between Hatsan PCP airguns and standard filling equipment. The coupling features a male Foster fitting with brass construction and integrated O-ring seals, designed to handle typical PCP operating pressures up to 300 bar.

Construction and materials

The coupling body is machined from brass with a silver finish. Internal O-rings create an airtight seal during connection, while the self-sealing Foster mechanism prevents air loss when disconnecting. The male thread configuration fits directly onto Hatsan fill ports without additional adapters.

Application and use

This coupling simplifies the filling process for PCP airgun users who switch between different air sources. The Foster quick-connect system allows tool-free attachment to hand pumps, dive tank hoses, or direct compressor lines. The audible click confirms secure connection, while disconnection requires only a simple pull-back motion.

Integration and compatibility

The nipple mounts directly to Hatsan PCP airguns with compatible fill ports. It accepts all standard female Foster fittings commonly found on PCP filling equipment. Once installed, users can interchange between various air sources without removing the coupling from the rifle.
