Product Description

O-RING Specifications

This replacement seal is designed for use in a variety of pneumatic tools, including both nail guns and staplers. It serves a vital function by creating an airtight seal—most commonly installed on the piston in nail guns and on the cylinder in staplers. This helps maintain consistent air pressure and tool performance. Over time, seals can wear out, crack, or lose their elasticity, which may lead to reduced efficiency or air leaks. If your tool is underperforming, replacing worn seals like this one can help restore its functionality. This seal is sold individually and measures 1.484 inches in outer diameter with a thickness of 0.139 inches, ensuring a snug and reliable fit during installation.
