Description

The HW100 O-Ring 12×1.1 is a precision sealing component used in the Weihrauch HW100 PCP air rifle platform. This small but critical seal helps maintain airtight operation within the rifle’s internal system, preventing pressure loss and ensuring consistent performance. Manufactured to match original specifications, it is typically replaced during routine maintenance or when servicing the rifle’s valve and internal assemblies. Compatible with multiple HW100 variants, this O-ring is commonly included in professional service kits used to restore the rifle to optimal working condition.
