Description

The Reximex O-Ring Set (Model REX-004) is a collection of high-quality spare O-rings engineered for use with Reximex RP and RPA PCP air pistols. These seals are used in various parts of the pneumatic system such as the fill probe seals, valve seals, and other high-pressure connection points. Over time, O-rings can wear or dry out, leading to air leaks or reduced performance; having a proper replacement set ensures that your airgun maintains reliable sealing and optimal pressure retention — essential for consistent shooting performance.

This set is ideal for shooters who perform regular maintenance on their Reximex firearms, or anyone refilling or servicing their airgun components. Installing fresh O-rings can stop minor leaks around fill ports and moving parts and help prolong the life of your airgun’s pneumatic system.
