Nibco UCMIP12 Press X Mnpt Wrot Copper Union 1/2 Inches PC633-4

Product Description

The NIBCO UCMIP12 is a 1/2 inches Press x Male NPT Wrot Copper Union designed for professional plumbing and mechanical systems. This fitting is part of the NIBCO Press System and is built to connect a press-style connection to a threaded male connection without the need for flame, solder, or flux. That makes it a go-to choice for plumbers and pipefitters working in tight spaces, near flammable materials, or wherever open flame is not permitted or practical. The union design allows technicians to disconnect and reconnect a line without cutting pipe or damaging existing connections, making repairs and future service calls faster and cleaner. The fitting uses an inboard bead and an EPDM O-ring seal. When a pressing tool applies force to the fitting, the O-ring compresses tightly against the tube, creating a watertight seal in seconds. The result is a reliable, leak-free joint that holds up under real working conditions. This union is manufactured from Wrot Copper conforming to ASTM B75 Alloy C12200, a high-purity copper alloy known for its corrosion resistance and long service life in potable water and hydronic heating systems. It carries a pressure rating of 200 psi cold working pressure and a temperature range of -20 degrees F to 250 degrees F, making it suitable for a wide range of residential and commercial applications. The fitting is lead-free and dezincification resistant. It is third-party certified to NSF/ANSI 61 Annex G for potable water safety, as well as to UPC, CSA MSE 13, and PS-117. Plumbers, mechanical contractors, and service technicians trust NIBCO Press System fittings for speed, safety, and consistent performance on every job.
