Rehau 235381-021 Raupex Uv Shield Pexa Tube Blue 1 Inch X 20 Ft

Product Description

The REHAU 235381-021 Raupex UV Shield PEXa Tube is a 1 inch nominal size, 20 foot straight length of crosslinked polyethylene pipe designed for potable water plumbing systems. Color-coded blue for cold water identification, this PEXa tube meets the demands of residential and commercial plumbing installations where reliability and long service life are required. REHAU engineered this pipe using a PE 3306 crosslinked polyethylene formulation, which gives it superior flexibility compared to rigid copper or CPVC pipe. That flexibility makes it easier to route through walls, floors, and tight spaces without as many fittings, reducing both labor time and potential leak points on the job. The CTS (Copper Tube Size) outside diameter of 1-1/8 inches and a wall thickness of 0.125 inches conform to SDR9 dimensional standards, making it compatible with standard expansion and clamp-style PEX fittings widely used by plumbing professionals. One standout feature of the Raupex UV Shield line is its extended UV resistance. Most PEXa pipe manufacturers provide only one to six months of UV protection during storage or exposure on the job site. REHAU extends that protection to 12 months, giving contractors and plumbers added flexibility in scheduling and staging materials without worrying about UV degradation. This tube is certified for potable water use and meets ASTM F876, ASTM F877, ASTM F2657, CSA B137.5, and PPI TR-3 standards. It can also be used in radiant heating and hydronic applications, though heating systems require corrosion protection or isolation through a heat exchanger or fully non-ferrous components. With a temperature rating of 73.4 to 200 degrees Fahrenheit and a pressure rating of 80 to 160 psi, this pipe handles the demands of both domestic water supply and low-temperature heating loops. It is a proven, cost-effective alternative to copper tubing for new construction and remodel plumbing work.
