Description

The HW100 O-Ring for Quick-Fill Adapter (Part No. 2710) is an original-spec sealing component used in the filling system of the Weihrauch HW100 air rifle. This O-ring is installed in the quick-fill adapter assembly, which connects the rifle’s air cylinder to a charging hose or filling system.

Its primary function is to maintain an airtight seal during the filling process, ensuring efficient air transfer and preventing pressure loss. Over time, repeated filling cycles and high-pressure air exposure can wear the seal, making periodic replacement important to keep the filling system functioning correctly. The part is identified in the HW100 schematic as the O-ring associated with the Schnellfülladapter (quick-fill adapter) assembly.
