Ram Tactical | O-Ring Fill Nipple Hatsan | 4 pcs | Black

Hatsan O-Rings for Fill Nipple – Rubber sealing rings for PCP air rifles

These O-rings from RAM Tactical are designed for Hatsan PCP air rifle fill nipples. The set contains 4 rubber O-rings that create an airtight seal between fill nipple and filling hose. Essential for maintaining pressure integrity up to 250 bar during cylinder filling operations.

Construction and materials

Each O-ring is manufactured from black rubber with precise dimensions for Hatsan fill nipples. These sealing rings form the critical barrier between high-pressure air systems and atmosphere. The material withstands repeated compression cycles and maintains flexibility across standard operating temperatures for PCP applications.

Application and use

These O-rings serve PCP shooters who operate Hatsan air rifles. Installation requires no special tools – remove the worn O-ring from the fill nipple groove, position the replacement ring evenly, and ensure proper seating. Regular inspection and replacement prevent air leakage when connecting filling equipment to the rifle.

Integration and compatibility

The O-rings fit all Hatsan PCP models with standard fill nipples. Compatible with common filling hoses equipped with Foster-type quick-connect couplings. Each set provides sufficient rings for multiple replacements across different rifles or as spare inventory for field maintenance.

Maintenance and lifecycle

O-rings require periodic replacement when compression set or surface degradation occurs. Signs include air leakage during filling or visible cracks in the rubber. Store spare O-rings in a cool, dry environment away from direct sunlight to maximise service life.
