Sealing Ring BF 1/8 BSP – Essential Component for Your HPA or PCP Setup

This sealing ring from BF is a small but crucial component for leak-proofing your filling system. The hardseal sealing ring is specifically designed for 1/8 BSP thread and is placed between the quick coupler and fill nipple. Whether you're working with a PCP air rifle, HPA airsoft setup or diving cylinder connections - this component ensures a reliable seal during filling.

Technology and Application

This sealing ring features a robust hardseal construction specifically suitable for 1/8 BSP thread connections. The metal outer section with rubber inner ring ensures optimal pressure resistance at high working pressures up to 300 bar. The ring effectively seals between the quick coupler and fill nipple, preventing air leakage during filling of your PCP or HPA system.

Ease of Use and Integration

This component integrates seamlessly into existing filling systems with 1/8 BSP connections. You simply place the ring between the quick coupler and fill nipple before tightening. The hardseal construction allows for reuse, although we recommend replacing the ring periodically with intensive use. This type of seal is compatible with standard Foster-type quick couplers and most PCP fill nipples.

Who Is This Component For?

This sealing ring is indispensable for PCP shooters who fill their air rifle via a diving cylinder or compressor, airsofters with HPA replicas who want a leak-free filling connection, and technicians who maintain filling systems. Users who notice that their current seal is worn or leaks air during filling will also benefit from this replacement ring.
