Nibco UCFIP34 Wrot Copper Press X Female Npt Union 3/4 Inches

Product Description

The NIBCO UCFIP34 is a wrot copper press x female NPT union fitting designed for use in plumbing and mechanical systems where a fast, reliable connection is required. This 3/4 inch union is part of the NIBCO Press System, a widely trusted method among plumbing professionals for joining copper tubing without open flame, solder, or flux. The fitting features an inboard bead and EPDM O-ring that compresses tightly around the tube wall when a standard press tool is applied. The result is a watertight, leak-free seal completed in seconds. This makes it a go-to solution for repairs and new installations in tight spaces or areas where flame cannot be safely used. One end connects via press to copper tubing, while the other end features a female NPT threaded connection. This combination allows plumbers and pipefitters to transition between a press system and a threaded connection with a single fitting. The union design means the line can be disconnected and reconnected for repairs or replacements without cutting or damaging surrounding pipe. The fitting is manufactured from ASTM B75 Alloy C12200 wrot copper, which provides excellent corrosion resistance and long service life in both hot and cold water applications. It is rated for operating pressures up to 200 psi cold working pressure and handles temperatures from -20 to 250 degrees Fahrenheit. The fitting is lead-free and dezincification resistant, meeting the material standards required for potable water systems. Domestic manufacture ensures consistent quality control. This fitting is well suited for residential and commercial plumbing repairs, HVAC hydronic systems, and mechanical piping where threaded and press connections must interface.
