The HW100 O-Ring 13×2 (Part No. 2704) is an original-spec replacement sealing component designed for the Weihrauch HW100 PCP air rifle platform. Positioned within the adaptor assembly (Adaptor A), this O-ring ensures a secure and airtight seal that helps maintain consistent air pressure and efficient rifle operation. Manufactured to match factory specifications, it is commonly replaced during routine servicing or full seal kit maintenance of the HW100 series.
