## Long description

Pipe end size: 22 mm

How to use
Ensure the pipe and threaded fitting are clean and free of debris before installing the coupling sleeve. Prepare the 22 mm pipe end according to the pipe system requirements (deburr, cut squarely, and, if required, press or solder per system type).

Verify the connection for leaks after pressurizing the system.
Usage recommendations
Use the coupling sleeve within the pressure and temperature limits of the overall plumbing or heating system and follow local plumbing codes. Select compatible pipe materials and installation methods (press, solder, or compression) as required by the specific 22 mm pipe system in use. Regularly inspect threaded connections for signs of wear or leakage during scheduled maintenance.
