Viega VIEGUCMIP114 Propress 79745 Bronze Pipe Union 1-1/4 Inches Press X Mnpt Lead Free

Product Description

The Viega VIEGUCMIP114 is a lead free bronze pipe union from the ProPress product line, referenced under manufacturer part number 79745. This fitting is designed for professional plumbing and mechanical systems where a reliable, removable connection between two pipe segments is required. The union configuration allows technicians to disconnect and reconnect piping runs without cutting or soldering, making it a practical choice for maintenance-intensive systems and retrofit work.

This union features a Press x MNPT end style, combining a press-fit connection on one end with a male national pipe taper thread on the other. The press end uses Viega ProPress technology, which allows the fitting to be secured using a press tool rather than an open flame, eliminating torch work on the job site. This is especially valuable in occupied buildings, near flammable materials, or wherever hot work permits are a concern. The MNPT end threads directly into female-threaded components such as valves, pumps, or equipment ports.

The fitting has a nominal size of 1-1/4 inches and an overall length of 3.52 inches. It is rated for working pressures up to 200 psi and is suitable for operating temperatures ranging from 0 to 250 degrees Fahrenheit. The bronze construction provides strong corrosion resistance and long service life in both hot and cold water applications. Lead free compliance makes this fitting appropriate for potable water systems, meeting modern plumbing code requirements.

HVAC technicians, plumbers, and mechanical contractors use ProPress unions like this one in hydronic heating systems, chilled water lines, domestic water distribution, and commercial plumbing installations. The press connection reduces installation time significantly compared to traditional sweat fittings.
