Afdichtingsring BF 1/8 BSP – Hardseal sealing ring for HPA/PCP filling systems

This BF sealing ring is a critical component for leak-free operation of filling systems. Designed for 1/8 BSP thread connections, it sits between the quick-connect coupling and fill nipple. The hardseal construction handles pressures up to 300 bar, making it suitable for PCP airguns, HPA airsoft setups, and scuba tank connections.

Construction and materials

The ring features a hardseal construction with a metal outer body and rubber inner seal. This dual-material design ensures optimal pressure resistance at high working pressures. The silver finish indicates the metallic component, while the internal rubber element provides the actual sealing properties. Built specifically for 1/8 BSP threaded connections, it maintains dimensional stability under pressure.

Application and use

This sealing ring prevents air leakage during filling operations for PCP airguns and HPA systems. Install it between the quick-connect coupling and fill nipple before tightening. The component is essential for users filling from scuba tanks or compressors, ensuring efficient pressure transfer without losses. Technicians maintaining filling systems rely on these rings for reliable connections.

Integration and compatibility

Compatible with standard Foster-type quick couplings and most PCP fill nipples using 1/8 BSP thread. The ring integrates seamlessly into existing filling setups without modifications. Works with both manual and automated filling systems operating within the 300 bar pressure range.

Maintenance and lifecycle

The hardseal construction allows for reusable application, though periodic replacement is recommended with intensive use. Inspect the rubber seal element for wear or deformation after extended service. Replace immediately if air leakage occurs during filling operations to maintain system efficiency.
