94826021 - AirPro X4000 Replacement Piston Kit with O-Ring

Get Your Tool Back to Work

When your AirPro X4000 starts losing its punch or feels sluggish, the internal piston is often the culprit. Over time, the constant cycling wears down the piston surface and the O-ring seal, leading to air leaks and a lack of power. The AirPro X4000 Piston Assembly with O-Ring is the direct replacement you need to fix the problem and get back to grinding, chipping, or cutting.

This kit comes ready to install with a new, durable piston and a fresh O-ring. It's designed to fit perfectly into your X4000, sealing the air chamber tight so you get full compression with every trigger pull. Don't struggle with a weak tool that slows down your workflow. Swapping out the piston is a straightforward repair that can save you the cost of buying a brand-new tool.

Whether you are working in a fabrication shop or on a heavy industrial site, keeping your pneumatic tools in top shape is key to efficiency. This assembly restores the hard-hitting action you expect from AirPro, ensuring your tool is ready for the toughest jobs. Make sure to lubricate the new piston with quality air tool oil during installation for the best results.
