Extension Hose Filling Kit | 1.5m | Best Fittings – High-pressure filling hose for PCP and HPA systems

This extension hose is a reinforced microbore filling hose designed for PCP air rifles and HPA systems. The 1.5 metre length provides flexibility when filling from diving cylinders or compressors, while the kevlar-braided construction supports 400 bar working pressure for demanding compressed air applications.

Construction and materials

The hose features a 2mm inner diameter with kevlar braiding for maximum durability under high pressure. Both ends are fitted with 1/8" BSP connections using galvanised steel fittings, ensuring reliable sealing up to 400 bar (5800 PSI). A strain relief spring at the cylinder end prevents kinking and extends service life during frequent use.

Application and use

This extension hose is used by PCP shooters requiring additional reach when filling air rifles, or users who need to position their diving cylinder at a distance. Airsoft players with HPA replicas operating from external air sources benefit from the added length and flexibility. The microbore design minimises air volume within the hose, reducing waste during disconnection.

Integration and compatibility

The hose integrates with existing filling sets through standard 1/8" BSP connectors. It functions between diving cylinders and fill adapters, or as an extension between compressors and PCP air rifles. The black kevlar construction matches most setups while providing visual durability indicators.
