Description

The HW100 O-Ring 8×1.5 is an original-spec replacement sealing component designed for the Weihrauch HW100 series PCP air rifles. This O-ring is commonly located in the barrel sealing area of the rifle assembly, where it helps maintain a proper seal between internal components to ensure stable air pressure and consistent shot performance.

Manufactured to the factory dimension of 8 mm inner diameter with a 1.5 mm cross-section, this seal is built to handle repeated pressure cycles during operation. Over time, O-rings can wear due to compression, friction, and air pressure changes, making periodic replacement important during maintenance or servicing of the rifle.
