Snelkoppeling Foster Female – Quick disconnect coupling for PCP air rifles

This Foster-type female quick coupling from Best Fittings features 1/8" BSP thread and is designed for PCP air rifle filling systems. The coupling incorporates a built-in flow restrictor to prevent overpressure when filling from high-pressure sources like 200-300 bar diving cylinders.

Construction and materials

The coupling is manufactured in bronze with a female Foster connection on one end and male 1/8" BSP thread on the other. The integrated flow restriction mechanism automatically regulates filling speed, protecting internal components from pressure damage during rapid filling operations.

Application and use

This coupling mounts directly onto PCP air rifle fill ports for connecting to high-pressure air sources. The Foster system enables tool-free connection and disconnection of fill hoses. It's commonly used for filling PCP rifles from diving cylinders, compressors, or portable air tanks equipped with Foster male connectors.

Integration and compatibility

The coupling fits air rifles with 1/8" BSP female threaded fill ports, including models from Benjamin, Crosman, and Daystate. To complete the filling setup, you'll need a fill hose with a Foster male connector. The coupling works with standard Foster quick-connect systems used throughout the PCP industry.
