This piston O-ring creates a tight seal between the piston and cylinder, allowing proper air pressure to build for strong and consistent fastening performance. Made from durable rubber, it is designed to withstand repeated use while maintaining reliability. Replacing a worn or damaged O-ring can restore driving power and help prevent air leaks, ensuring your tool operates effectively.
