Uponor f1921250 Aquapex Pex-a Pipe 1-1/4 in 20 Ft White

Product Description

The UPONOR f1921250 is a 1-1/4 inch diameter AquaPEX PEX-A pipe sold in 20-foot lengths in white. PEX-A is manufactured using the Engel method, which produces a highly flexible, cross-linked polyethylene pipe with superior resistance to stress cracking and freeze damage compared to PEX-B or PEX-C. This pipe is a core component in radiant heating, potable water distribution, and hydronic systems. Licensed plumbers and mechanical contractors specify PEX-A tubing for its ability to be expanded with a proper expansion tool, creating a reliable, leak-resistant connection at fittings.

This pipe is suitable for residential and light commercial plumbing and radiant heating applications. The 1-1/4 inch diameter makes it appropriate for main distribution runs, manifold supplies, and larger branch lines where flow capacity is a priority. White color coding is commonly used for cold-water lines, though the pipe itself is rated for both hot and cold potable water service. Installers working on hydronic radiant floor systems, snow-melt systems, or domestic water distribution will find this size and length practical for standard rough-in work.

Key Features

• PEX-A construction using the Engel method for maximum flexibility and cross-link density
• 1-1/4 inch diameter supports higher-flow distribution runs and main supply lines
• 20-foot length suits standard rough-in cuts with minimal waste
• White color for easy identification in multi-line installations
• Compatible with expansion-style fittings for a secure, reliable joint

Compatibility

Designed for use in PEX-A plumbing and radiant heating systems requiring 1-1/4 inch AquaPEX tubing. Intended for use with compatible PEX-A expansion fittings and tools rated for this pipe diameter and material type.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water supply before cutting or joining any pipe in an existing system. Use only expansion tools and fittings rated specifically for PEX-A pipe to ensure a code-compliant, leak-free connection. Avoid exposing PEX pipe to direct UV light for extended periods during storage or installation.
