Mordax Quick-Connect Fill Nipple – Essential PCP airgun filling interface

The Mordax fill nipple from Western Airguns is a precision-engineered quick-connect fitting designed for PCP air rifles and pistols. This component serves as the critical interface between your PCP system and high-pressure air sources, featuring Foster-type compatibility and integrated O-ring sealing for leak-free operation.

Construction and materials

Built with a metal body and precision-machined threads, this fill nipple incorporates an internal O-ring seal for reliable air retention. The optimised flow channel ensures unrestricted airflow during filling operations, preventing pressure drops and enabling efficient charging cycles.

Application and use

This fill nipple installs directly into PCP airguns' fill ports, suitable for both recreational and competition shooters requiring reliable self-filling capabilities. Compatible with standard Foster quick-disconnect fittings, it works with conventional fill hoses from dive tanks, compressors, or hand pumps. Originally designed for Western Airguns models like the Rattler and Sidewinder, it fits any PCP system with matching thread specifications.

Integration and compatibility

The nipple features universal Foster-type connection standards, ensuring broad compatibility with PCP filling equipment. Installation requires threading the nipple into the designated fill port using appropriate tools. The quick-connect mechanism engages automatically when the fill probe slides over the nipple, releasing via the collar retraction method once target working pressure is achieved.
