The 1/2 in. Polypropylene Compression Union is a polypropylene compression union fitting that allows in-line disconnection of the tubing run for service without disturbing surrounding fittings. Polypropylene construction provides strong chemical resistance for acids, bases, and chlorinated water service where brass would corrode or leach.
