BF O-ring for DIN air bottle connection

BF O-ring for DIN air cylinder connection – O-ring for your HPA or PCP setup

This BF O-ring is an essential replacement component for DIN connections on compressed air cylinders. Whether you are working with HPA systems for airsoft or filling PCP air rifles, a properly functioning O-ring ensures an airtight seal between your filling set and the cylinder. It prevents air leakage during filling and guarantees a secure connection.

Technology and application

This O-ring is made from rubber and specifically designed for DIN connections. DIN (Deutsches Institut für Normung) is a widely used standard for compressed air cylinders, especially for diving tanks and HPA tanks up to 300 bar. The O-ring serves as a seal in the threaded section of the DIN connection, where it provides a hermetic seal between the filling set and the cylinder connection.

Ease of use and integration

This part is used as a replacement component when the original O-ring is worn or damaged. With regular use of filling sets, O-rings become compressed or hardened over time, causing them to lose their sealing function. This BF O-ring fits directly into standard DIN filling sets and is compatible with all common DIN compressed air cylinders, regardless of whether they are used for HPA airsoft or PCP applications.

Who is this part intended for?

This O-ring is intended for users working with DIN connections on compressed air cylinders. Think of airsoft players with HPA setups who fill their tanks via a DIN filling set, PCP shooters who fill their air rifles from a diving cylinder, or technicians maintaining filling stations. Regular replacement of O-rings is part of preventive maintenance and prevents unexpected leaks during use.
