Introducing the Upgraded Piston Seal by Custom Air Seals Australia, specifically designed for Air Arms, Gamo & Stoeger spring rifles. Precision machined using high-quality polyurethane, this seal features a steep cut-away taper, minimizing sealing contact and friction. With its sealed face design, it reduces lost volume and air loss, ensuring improved consistency for optimal performance. Elevate your spring rifle with this advanced piston seal upgrade.

Please de-burr your cocking slot, trigger cut out and cross pin hole, before installing piston and piston seal.

Before Purchasing please measure the original piston seal and piston. This piston seal may need sizing to fit your air rifle correctly
