The MK5 Quick Service Kit from Hill is a comprehensive seal replacement set designed specifically for servicing the Hill MK5 hand pump. This maintenance kit contains all essential seals and O-rings required to restore your PCP hand pump to optimal working condition, preventing air leakage and restoring factory-level pumping efficiency.

Construction and materials

This service kit includes a complete set of precision-fitted seals for the Hill MK5 hand pump. Components include various diameter O-rings, a brass fill nipple with blue seal, and PTFE rings for optimal sealing performance. All parts are manufactured from durable materials engineered to withstand the high pressures generated when filling PCP air rifles up to 200-250 bar. Each component is precisely dimensioned to match the internal specifications of the MK5 pump assembly.

Application and use

This maintenance kit serves as a complete replacement set for periodic servicing or pressure loss troubleshooting. The seals install easily using standard tools and fit directly onto existing pump components. The included fill nipple features standard 1/8" BSP threading, ensuring universal compatibility with various PCP fill hoses and adapters.

Integration and compatibility

Designed exclusively for the Hill MK5 hand pump, this kit ensures direct fitment without modifications. The standardised 1/8" BSP connection maintains compatibility with common PCP filling accessories. Regular replacement of these components maintains maximum pumping efficiency and prevents premature wear of costlier pump parts.

Maintenance and lifecycle

Regular servicing with this kit is recommended when pumping efficiency decreases, air leakage occurs, or additional pump strokes are needed to reach target pressure. Timely seal replacement extends the operational lifespan of your MK5 pump and maintains consistent performance throughout its service life.
