Description

The KalibrGun Cricket O-Ring Set for 5.5 – C55 is a service and maintenance kit containing replacement sealing rings used in the internal air system of the KalibrGun Cricket PCP air rifle platform. In PCP rifles, O-rings are critical components that create airtight seals between high-pressure air components such as the air cylinder, valve assembly, regulator, filling port, and pressure gauge connections.

During operation, the rifle stores compressed air at pressures that can reach approximately 300 bar, and the O-rings ensure that the system remains sealed while allowing moving components to operate smoothly. Over time, seals can deteriorate due to pressure cycles, friction, or environmental factors. When this occurs, the rifle may develop air leaks or inconsistent performance, making seal replacement necessary.

The C55 O-ring kit provides the correctly sized seals for servicing the 5.5 mm version of the Cricket platform. By replacing worn or damaged seals, the air rifle’s pressure system can be restored to proper working condition, ensuring consistent velocity and efficient air usage. Full O-ring replacement kits typically contain multiple seals covering all internal sealing points of the rifle.
