Replacement Valve stem and seal for the Weihrauch HW100 air rifle.
If your rifle is leaking air down the barrel it is this part and the valve seat that are no longer creating a seal. It is then recommended to replace both.

Caliber and power specific, we have UK spec (12ftlb) versions in stock in .177 (4.5mm) and .22 (5.5mm). Other power settings and calibers available as special order, please contact us.
