PexRite Pex/Copper/CTS Isolator Insert, 1" Blue

PexRite Pex/Copper/CTS Isolator Insert, 1" Blue

The 426-RB PexRite PEX/Copper/CTS Isolator Insert (1" Blue) is a through-stud tubing isolator designed to protect and position piping in metal stud installations. Made from durable polypropylene, it prevents metal-to-metal contact between tubing and studs, reducing vibration, wear, and those mysterious pipe noises that tend to show up right after the drywall goes up. The blue color designates cold-water lines, making identification quick during installation and future maintenance. It’s engineered to work with standard metal stud cutouts and PexRite/HoldRite bracket systems, keeping piping properly aligned and protected inside the wall.
