The REHAU 235371-021 is a 3/4-inch blue PEX pipe with UV shield protection, sold in 20-foot lengths and packaged 25 pieces per bag. PEX pipe is a cross-linked polyethylene product used in potable water distribution, hydronic heating, and radiant floor systems. The blue color coding indicates cold-water service lines, making identification straightforward during rough-in and inspection. The UV shield construction helps the pipe resist degradation from sunlight exposure during job-site storage or in applications where temporary light exposure is a concern. Licensed plumbers and mechanical contractors are the typical installers for this product type.
This pipe is suited for residential and light commercial plumbing installations where flexible, freeze-resistant water supply lines are required. It is appropriate for use in walls, floors, and crawl spaces as part of a domestic cold-water distribution system. The 20-foot stick length works well for branch runs and direct home-run layouts. The 25-piece-per-bag packaging allows contractors to purchase in quantities that match typical job-site needs without excess material handling.
Designed as an OEM-style PEX pipe for use with standard 3/4-inch PEX fittings and installation systems compatible with ASTM F876 and F877 rated PEX pipe.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before making any connections. Use only fittings and tools rated and listed for use with PEX pipe, and verify that the connection method (expansion, crimp, or clamp) matches the fitting system on the job. Avoid leaving unshielded PEX exposed to prolonged direct sunlight beyond what the UV shield rating supports, and follow local code requirements for pipe support spacing.
