MK1 - MK2 Piston Seal Kit | Hill – Maintenance Product for Your HPA or PCP Setup

The MK1 - MK2 Piston Seal Kit from Hill contains three replacement piston seals for Hill hand pumps. These seals are essential for the maintenance of your hand pump, which you use for filling PCP air rifles and HPA systems. A properly functioning piston seal ensures efficient pumping without pressure loss.

Technology and Application

These piston seals are the most important component of your Hill hand pump. They provide the airtight seal between the piston and cylinder wall during pumping up to 200-300 bar. The seals are made from wear-resistant material that can withstand the high pressures generated when filling PCP cylinders and HPA tanks. Wear occurs due to friction, overheating, and insufficient lubrication during intensive use.

Ease of Use and Integration

This maintenance product is specifically designed for Hill hand pumps of the MK1 and MK2 type. Installation is easy to perform with basic tools. Symptoms indicating replacement is necessary: resistance during the upward pump stroke, the handle dropping back, or pressure loss while pumping. With three seals in the kit, you have enough spares for multiple maintenance rounds.

Who Is This Maintenance Product For?

This seal kit is essential for PCP shooters and HPA users who regularly use their Hill hand pump. Whether you are filling your PCP air rifle for precision shooting or your HPA tank for airsoft, a well-maintained pump prevents frustration and extends the lifespan of your equipment. Technicians maintaining multiple pumps benefit from the supply of three seals.
