Description

The Cricket O-Ring Set for 4.5 is a maintenance kit intended for servicing the internal sealing components of KalibrGun Cricket PCP air rifles. In a pre-charged pneumatic airgun, multiple O-rings are used throughout the high-pressure air system, including the air cylinder, valve assembly, regulator, filling port, and pressure gauge connections.

These elastomer seals ensure airtight operation by preventing compressed air from escaping the reservoir and internal components. Over time, O-rings can wear out due to repeated pressurization cycles, exposure to high pressure (often up to 300 bar in PCP rifles), or natural material aging. When seals degrade, the rifle may experience air leaks, inconsistent velocity, or pressure loss.

The C45 O-ring kit provides replacement seals that match the sizes specified in the KalibrGun Cricket service diagrams. By replacing worn seals, the rifle’s air system can be restored to proper operating condition, ensuring reliable pressure retention and consistent shot performance.
