PCP Pump Dry Pac Kit | MK4-MK5 | Hill – Moisture removal system for PCP air rifles

The Hill Dry-Pac Kit is a moisture removal system designed for PCP shooters using manual pumps. This maintenance accessory removes up to 90% of harmful moisture from compressed air before it reaches your air rifle, specifically engineered for Hill MK4 and MK5 hand pumps.

Construction and materials

The system features a molecular sieve that absorbs moisture from compressed air during pumping. A transparent housing provides visual indication of saturation levels, changing from orange to green when the desiccant becomes saturated. The unit connects between pump and fill hose via a quick-release coupling, built to withstand high pressures during filling operations.

Application and use

This moisture removal system is essential for maintenance of PCP air rifles, particularly in humid environments. It prevents rust formation and extends the lifespan of PCP reservoirs by ensuring dry air fills. The compact design allows unobstructed pumping while effectively filtering moisture from the air supply.

Integration and compatibility

The Dry-Pac Kit integrates seamlessly with Hill MK4 and MK5 hand pumps without requiring modifications. Installation involves connecting the unit inline between pump and fill hose. Refill sachets are included for easy desiccant replacement – simply open the housing and swap the saturated material.

Maintenance and lifecycle

The system requires periodic desiccant replacement when the indicator shows saturation. Regular monitoring of the colour indicator ensures optimal performance. The robust construction withstands repeated high-pressure cycles typical of PCP filling operations.
