BF | O-ring for DIN Air Tank Connection | Black

BF O-ring voor DIN luchtfles aansluiting – Essential seal for HPA and PCP systems

This BF O-ring is a replacement component for DIN connections on compressed air cylinders. The ring provides an airtight seal between filling equipment and cylinder valves, preventing air leakage during filling operations. Made from rubber, it ensures secure connections for HPA airsoft systems and PCP air rifle filling setups.

Construction and materials

The O-ring is manufactured from rubber in black colour, designed specifically for DIN connection standards. DIN (Deutsches Institut für Normung) is widely used for compressed air cylinders, particularly diving tanks and HPA tanks up to 300 bar. The ring fits within the threaded section of DIN connections, creating a hermetic seal between filling adapters and cylinder valves.

Application and use

This component serves as a replacement part when original O-rings become worn or damaged. Regular use of filling equipment causes O-rings to compress or harden over time, reducing their sealing effectiveness. Users of HPA airsoft setups, PCP shooters filling from diving cylinders, and technicians maintaining filling stations require periodic O-ring replacement as part of preventive maintenance.

Integration and compatibility

The O-ring fits standard DIN filling sets and is compatible with all common DIN compressed air cylinders, regardless of whether they're used for HPA airsoft or PCP applications. Installation is straightforward – the ring seats directly into the DIN connection point. Supplied as 1 piece per package.
