The 425-RR PexRite PEX/Copper/CTS Isolator Insert (3/4" Red) is a through-stud tubing isolator designed to protect and support piping in metal stud installations. Constructed from durable polypropylene, it helps isolate copper, PEX, and CPVC tubing from metal studs, reducing vibration, wear, and the kind of rattling noises that make homeowners wonder if there’s a plumbing poltergeist in the wall. The red color indicates hot-water lines, making identification easy during installation and service. Designed to integrate with PexRite/HoldRite bracket systems, it keeps pipes aligned, protected, and exactly where they belong inside the wall.
