Uponor F4921000 Aquapex Straight Tubing 1 in 20 Ft Pex-a

Product Description

The UPONOR F4921000 is a 1-inch nominal AquaPEX straight tubing section manufactured using the Engel process, which produces a PEX-a cross-linked polyethylene pipe. PEX-a offers superior flexibility and shape memory compared to PEX-b or PEX-c alternatives, making it well suited for potable water distribution and hydronic heating applications. Each section measures 20 feet in length with an inside diameter of 0.862 inches and an outside diameter of 1.125 inches. The domestic origin and Engel-process crosslinking are key quality indicators for specifying engineers and licensed plumbers working on residential and light commercial systems.

This tubing is used in residential and light commercial potable water supply lines, hot and cold distribution systems, and radiant floor heating or hydronic panel systems. The straight 20-foot stick format is preferred on job sites where coil memory would complicate installation in tight mechanical rooms or when running longer straight runs through framed walls and joists. The white and red color coding helps tradespeople quickly identify hot and cold lines during rough-in.

Compatibility

Designed for use with Uponor AquaPEX expansion-style fittings and tools sized for 1-inch nominal PEX-a tubing. Consult Uponor system documentation for confirmed fitting and manifold compatibility before installation.

Installation Notes

Installation of PEX tubing should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off the water supply and relieve system pressure before cutting into any existing line. Use only expansion or crimp tooling rated for 1-inch PEX-a; do not use open-flame tools near installed tubing. Support spacing, bend radius limits, and burial requirements must comply with the authority having jurisdiction.
