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

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

The 424-RB PexRite PEX/Copper/CTS Isolator Insert (1/2" Blue) is a through-stud tubing isolator designed to protect and properly position piping in metal stud installations. Constructed from durable polypropylene, it isolates PEX, copper, and CPVC tubing from direct contact with metal studs, helping reduce vibration, noise, and long-term pipe wear. The blue color designates cold-water lines, making identification quick during installation and service. Designed to integrate with PexRite/HoldRite bracket systems, this insert helps keep piping aligned and protected within the wall—because plumbing should move water quietly, not audition for a percussion section behind the drywall.
