The REHAU 235371-102 is a 3/4 inch RAUPEX Red UV Shield PEXa pipe sold in a 100 foot coil (30.5 meters). It is designed for plumbing, hydronic heating, and radiant floor heating systems where flexibility, durability, and long-term performance are required. REHAU manufactures this pipe using a high-pressure peroxide extrusion method, also known as the PEXa process. This method produces the highest and most consistent level of crosslinking available in crosslinked polyethylene pipe. Higher crosslink density means better resistance to heat, pressure, and long-term stress. Plumbers, mechanical contractors, and radiant heating installers rely on PEXa pipe for its ability to flex without cracking and to handle demanding temperature and pressure conditions. The red color coding helps installers identify hot water lines at a glance, which speeds up rough-in work and reduces errors on the job. The UV Shield formulation protects the pipe from ultraviolet light degradation during storage and installation, making it suitable for job sites where the pipe may be exposed to sunlight before being concealed. This pipe has an outer diameter of 0.875 inches and a flow capacity of 0.0189 gallons per foot, which is standard for 3/4 inch PEX applications. It is lead-free and made in the USA, meeting the requirements for potable water systems and green building standards. The 100 foot coil format is practical for residential and light commercial jobs, offering enough length for most hydronic loops or plumbing runs while keeping material handling manageable. REHAU RAUPEX pipe is compatible with REHAU expansion fittings and other PEXa-rated connection systems. It meets ASTM F876 and ASTM F877 standards for PEX tubing used in plumbing applications.
The REHAU 235371-102 RAUPEX Red UV Shield PEXa pipe delivers proven flexibility, UV protection, and high crosslink density in a convenient 100 foot coil. It is a dependable choice for plumbers and hydronic heating contractors working on potable water, radiant floor, and heating distribution systems.
