PexRite Pex/Copper/CTS Isolator Insert, 1/2" Red

PexRite Pex/Copper/CTS Isolator Insert, 1/2" Red

The 424-RR PexRite PEX/Copper/CTS Isolator Insert (1/2" Red) is a through-stud tubing isolator designed to protect and properly position piping in metal stud installations. Made from durable polypropylene, it helps separate PEX, copper, or CPVC tubing from metal studs, reducing vibration, wear, and long-term pipe damage. The red color indicates hot-water lines, allowing quick identification during installation or service. Designed to work with PexRite/HoldRite bracket systems, this insert keeps piping aligned and protected inside the wall—because pipes should move water quietly, not announce themselves every time someone runs the hot tap.
