Rehau 499847-001 F1960 Polymer Run Reducing Tee 1-1/2x3/4x1-1/2 in

Product Description

The REHAU 499847-001 is an F1960 polymer run reducing tee designed for PEX expansion plumbing systems. This fitting connects a 1-1/2 inch main run to a 3/4 inch branch while maintaining the 1-1/2 inch run, allowing flow reduction without breaking the main line. It is manufactured from polymer construction suited for potable water and hydronic piping applications. Licensed plumbers install this fitting using the ASTM F1960 cold-expansion method, which requires an expansion tool and compatible PEX-a tubing. The fitting is intended for in-wall, in-slab, or mechanical room piping where a reducing tee configuration is required.

This fitting is used in residential and light commercial plumbing systems that utilize the F1960 expansion-style PEX connection method. Typical applications include domestic hot and cold water distribution, radiant heating supply and return runs, and hydronic system branch takeoffs. The run reducing configuration is commonly specified where a full-port tee would oversize the branch connection, helping balance flow in multi-zone or trunk-and-branch layouts.

Key Features

• F1960 cold-expansion connection method for secure, leak-resistant joints
• Run reducing configuration: 1-1/2 inch run by 3/4 inch branch by 1-1/2 inch run
• Polymer construction compatible with PEX-a expansion plumbing systems
• No solder, flux, glue, or open flame required during installation
• Suitable for domestic water and hydronic piping applications

Compatibility

Designed as an OEM-style F1960 expansion fitting for use with PEX-a tubing in residential and light commercial plumbing systems requiring a 1-1/2 x 3/4 x 1-1/2 inch run reducing tee configuration.

Installation Notes

Installation must be performed by a licensed plumber in accordance with local plumbing codes and ASTM F1960 requirements. Shut off the water supply and depressurize the line before cutting into existing piping. An F1960-compatible expansion tool is required to expand the PEX-a tubing end before seating the fitting. Allow the fitting joint to contract fully before pressurizing the system.
