Uponor F1921250 Aquapex Pex Tubing 1-1/4 in 20 Ft White

Product Description

The UPONOR F1921250 is a straight-length AquaPEX tubing sold in 20-foot sections, sized at 1-1/4 inch nominal with an inside diameter of 1.104 inches and an outside diameter of 1.375 inches. Made from cross-linked polyethylene (PEX), this tubing is engineered for potable water distribution, hydronic heating, and radiant floor heating systems. Its white color coding is standard for cold-water or general-purpose lines. Licensed plumbers and hydronic system installers use this tubing in residential and light commercial construction where flexible, corrosion-resistant piping is required.

F1921250 is suited for hot and cold potable water supply, recirculation loops, and hydronic distribution manifold runs. The 1-1/4 inch nominal size handles higher flow demands typical of main distribution lines, branch headers, or commercial manifold feed lines. The 20-foot straight-length format supports installations requiring rigid staging or where coiled tubing would complicate layout, such as in mechanical rooms or long straight runs between manifolds.

Key Features

• 1-1/4 inch nominal PEX tubing with 1.104 inch ID and 1.375 inch OD for precise fitting compatibility
• 20-foot straight-length format simplifies staging and measurement in mechanical room installations
• Cross-linked polyethylene (PEX) construction resists corrosion, scaling, and chemical degradation
• White color designation for easy identification in multi-line potable water and hydronic systems
• Flexible enough to absorb expansion and contraction without fitting stress

Compatibility

Designed as an OEM-style replacement and standard-use PEX tubing for residential and light commercial plumbing and hydronic heating systems using 1-1/4 inch PEX fittings and expansion or crimp connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and ASTM F876/F877 standards for PEX tubing. Shut off the water supply and depressurize the system before cutting or connecting tubing. Use only fittings and connection methods rated and listed for PEX tubing at the applicable nominal size. Avoid contact with petroleum-based solvents, open flame, or UV exposure during storage and installation.
