Uponor F1921000 Aquapex Pex Tubing 1 in 20 Ft White

Product Description

The UPONOR F1921000 is a straight-length AquaPEX tubing section used in residential and commercial plumbing, hydronic heating, and radiant floor systems. Manufactured from cross-linked polyethylene (PEX), this tubing measures 1 inch nominal outside diameter with an actual inside diameter of 0.862 inches and an outside diameter of 1.125 inches. Each straight length runs 20 feet, making it well suited for longer runs where coiled tubing is less practical. The white exterior finish is standard for indoor potable water and hydronic distribution applications. Licensed plumbers and mechanical contractors are the primary installers of this product.

This tubing is designed for use in hot and cold potable water distribution systems, hydronic heating and cooling distribution loops, and snow-melt and radiant panel installations. Its straight-length format is commonly used in manifold-to-fixture runs, main distribution trunk lines, and mechanical room connections where rigid routing and minimal bending are preferred. The 20-foot stick length simplifies layout in open-wall or exposed-pipe installations.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor in accordance with local plumbing codes and ASTM F876/F877 standards. Shut off the water supply and depressurize the system before cutting into any existing lines. Use the appropriate PEX expansion tool or crimp ring tool matched to the fitting type and tubing size. Avoid kinking the tubing during bending; use bend supports or bend guides where directional changes are required.
