Description
Overview:
The Piston Cushion for Trelawny needle guns is a genuine Trelawny component (MPN 809 3004 / 8093004) that sits in the impact path of the air-driven piston to absorb shock and cushion each blow. Made from a tough, oil-resistant elastomer (rubber), it helps control vibration, protects internal parts and maintains smooth, reliable operation under continuous use. It is intended for handheld Trelawny pneumatic needle scalers used for rust, scale and coating removal on steel, stone and concrete. Manufactured to OEM tolerances for a precise fit, it supports consistent performance and reduced downtime. Replacing a worn cushion restores correct stroke, reduces metal-to-metal contact and extends the service life of the tool. This is a Genuine Part for assured compatibility and reliability.

Typical Applications:
Used during overhaul or routine servicing of Trelawny air needle guns in fabrication, shipbuilding, steelwork, plant maintenance and concrete preparation. Replacement is recommended when the tool shows harsh impact, increased vibration, reduced power or excess noise. Keeps needle scalers working efficiently for rust and paint removal, weld slag cleanup and surface keying on metal, masonry and concrete.
