MK5 Non-Return Valve Kit – Complete maintenance set for Hill MK5 hand pump

The MK5 Non-Return Valve Kit from Hill is a comprehensive maintenance set designed for the non-return valve of the Hill MK5 hand pump. This kit contains all essential components needed to replace and maintain the non-return valve, ensuring optimal performance when filling PCP air weapons and small HPA cylinders.

Construction and materials

The kit includes an Allen key, spring, O-ring, valve and various seals. Each component is manufactured to exact MK5 specifications. The non-return valve ensures compressed air flows in one direction only – from pump to PCP weapon or HPA bottle. Over time, wear can reduce valve effectiveness, resulting in pressure loss or inefficient pumping.

Application and use

This maintenance product is designed for straightforward installation in the Hill MK5 hand pump. The included Allen key enables disassembly and assembly without additional tools. Regular replacement of these wear-sensitive components prevents unexpected failure and maintains pumping efficiency for both recreational shooters and intensive training applications.

Integration and compatibility

The kit is specifically engineered for the Hill MK5 hand pump. All components are pre-matched to MK5 specifications, eliminating compatibility concerns. The O-ring and seals provide airtight closure while the spring delivers correct counter-pressure for the valve mechanism.
