Description

The HW100 O-Ring 3×1.5 is a precision replacement sealing component designed for the Weihrauch HW100 PCP air rifle platform. This O-ring is installed on the valve stem, where it plays an essential role in maintaining an airtight seal during operation. Correct sealing helps prevent pressure loss and ensures consistent performance of the rifle’s internal valve system. Manufactured to match factory specifications, this component is typically replaced during routine maintenance, servicing, or complete seal kit overhauls of the HW100 series rifles.
