Viega 25706 Pipe Union 3/4 Inch Press Carbon Steel

Product Description

The VIEGA 25706 is a 3/4 inch press-fit pipe union designed for carbon steel piping systems. A pipe union allows two sections of pipe to be joined and later disconnected without cutting the line, making it a practical fitting for service points and equipment connections. The press-fit end connection eliminates open-flame soldering or threading on-site, speeding up installation in both new construction and retrofit applications. Licensed plumbers and pipefitters working on hydronic heating, mechanical piping, and commercial plumbing systems are the primary installers of this fitting.

This union is suited for residential and light commercial hydronic and plumbing systems where carbon steel piping is specified. The 3/4 inch nominal size fits standard Schedule piping commonly found in hot water heating loops, chilled water distribution, and domestic water supply headers. Press-fit carbon steel fittings are frequently specified in mechanical rooms and tight spaces where torch work is restricted or prohibited by code.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with local plumbing codes and the applicable International Plumbing Code requirements. Depressurize and drain the system completely before installing or removing the union. A manufacturer-approved press tool with the correct jaw set for the fitting size is required to make a proper press-fit connection. Inspect the EPDM or o-ring seal for proper seating before pressing the joint.
