Foster Fill Nipple Bintac – 8mm connection for PCP air rifle systems

This fill nipple features an 8mm Foster-type connection for filling PCP air rifles. The nipple provides a leak-free coupling between your fill hose and the air cylinder, constructed from aluminum with a silver finish. The 8mm diameter matches standard quick-connect systems used in airgun applications.

Construction and materials

The nipple is manufactured from aluminum for durability and weight reduction. The 8mm diameter connection conforms to Foster coupling standards, ensuring compatibility with most PCP filling equipment. The component withstands fill pressures up to 300 bar, suitable for high-pressure air rifle systems.

Application and use

This fill nipple is designed for PCP air rifle filling operations. It mounts directly to the fill port of air tanks or rifles, enabling safe air transfer from high-pressure sources like compressors or dive bottles. The nipple serves both daily filling needs and replacement of worn fill connections.

Integration and compatibility

The nipple threads onto existing fill ports and accepts standard 8mm Foster quick-connect fittings. This universal sizing ensures compatibility with most PCP fill sets, compressor connections, and dive bottle adapters. Installation requires threading the nipple onto the fill port and clicking the Foster-equipped fill hose into place.
