Viega 20723 Propress Xl-c Copper Press Tee 4x4x3 in

Product Description

The VIEGA 20723 is a ProPress XL-C copper press tee designed for use in large-diameter press-fit piping systems. It features a 4 x 4 x 3 inch nominal configuration — full-port run connections at 4 inches with a 3-inch branch outlet — and uses a press end style that eliminates open-flame soldering. The fitting is manufactured from copper, making it well suited for potable water, HVAC hydronic, and mechanical piping applications. Licensed plumbers and pipefitters are the primary installers of this fitting.

This fitting is intended for commercial and large residential mechanical systems where 4-inch copper press piping is specified. The ProPress XL-C system is designed for high-flow distribution mains, hydronic heating and cooling loops, and similar large-bore installations. It is particularly common in situations where soldering is restricted by code, schedule, or site conditions. The press end style allows fast, repeatable connections without flux or heat.

Key Features

• Press end style eliminates open-flame soldering for faster, code-compliant installation
• 4 x 4 x 3 inch nominal size accommodates large-diameter main runs with a reduced branch outlet
• Copper construction provides corrosion resistance and compatibility with copper piping systems
• XL-C series rated for large-bore commercial and mechanical applications
• Consistent dimensional tolerances support reliable press tool engagement and leak-free seating

Compatibility

Designed as an OEM-style press fitting for use in 4-inch and 3-inch nominal copper press piping systems compatible with the Viega ProPress XL-C fitting series and corresponding press tooling.

Installation Notes

Installation must be performed by a licensed plumber or pipefitter using a calibrated press tool rated for the XL-C fitting series and the appropriate jaw or ring set for 4-inch and 3-inch copper press connections. Depressurize and drain the system completely before cutting into existing piping. Follow all applicable plumbing codes including IPC and local amendments for press-fit copper fittings. Do not attempt to press a fitting that has visible damage to the sealing element or the pipe end preparation.
