Maintain the performance and reliability of your Hill MK5 PCP hand pump with the Hill MK5 Non‑Return Valve Kit (Z5128‑250). This genuine Hill maintenance kit contains all the essential components required to restore the pump’s one‑way airflow system, ensuring efficient compression and preventing pressure loss during PCP air rifle filling.
The non‑return valve is a critical part of the MK5 pump’s internal mechanism, allowing air to flow from the pump into your cylinder while preventing backflow. Over time, wear can cause reduced sealing efficiency, leading to harder pumping or loss of pressure—this kit provides a complete set of replacement parts to solve those issues.
