AirCraft Gasket, Piston & O-ring Kit (6-12) For AT0019 (AT0019-SK02)

At a Glance: Seal-and-piston service kit (Parts 6–12) for the AirCraft AT0019—designed to restore compression, reduce air leaks and bring back crisp cycling.

Inside every pneumatic stapler is a fast-moving piston that relies on tight seals to build pressure and deliver a clean, confident drive. When gaskets and O-rings wear, you’ll usually notice air leaks, weak power, inconsistent firing, or a tool that feels “lazy” between shots. The AirCraft AT0019-SK02 Gasket, Piston & O-ring Kit covers parts 6–12 from the AT0019 spares diagram, giving you the core sealing components (and piston-related service parts) needed to refresh the working heart of the tool. It’s a smart maintenance kit for busy workshops and a go-to fix when performance starts dropping due to internal seal wear.
