Please Note: This seal/washer is the newer style piston seal that replaces the old style PTFE & cushion washer arrangement.
The Piston Seal/Washer seals the piston to drive air into the breech of the rifle and down the barrel. When changing the spring or tuning the rifle it is recommended to replace the Piston Seal/Washer because split, or damaged seals allow air to escape past the seal causing a loss of power and inconsistency of shot placement.
Suitable For the following Webley Air Rifles:
