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

This fill nipple provides a quick-connect solution for Hatsan PCP airguns, featuring a universal male Foster coupling. The brass construction with O-ring seals ensures airtight connections at working pressures up to 300 bar.

Construction and materials

Built from durable brass with integrated O-ring seals, this coupling utilises proven Foster quick-connect technology in a male configuration. The self-sealing mechanism prevents air loss during connection and disconnection. The silver finish provides corrosion resistance for long-term reliability.

Application and use

This coupling mounts directly onto the fill port of Hatsan PCP airguns. Once installed, users can switch between different fill sources in seconds without tools. The audible click confirms secure connection, while simple hand operation releases the coupling.

Integration and compatibility

The Foster male connector is compatible with all female Foster fittings found on hand pumps, scuba tank fill hoses, and direct compressor connections. This standardised interface ensures compatibility with most PCP filling equipment available in the market.

Maintenance and lifecycle

The O-ring seals require periodic inspection and replacement to maintain airtight performance. Regular cleaning of the coupling interface prevents debris accumulation that could compromise the seal integrity.
