Matco-norca cun03 1/2 Inch C X C Wrot Copper Union

Product Description

The Matco-Norca cun03 is a 1/2 inch wrot copper union fitting designed for sweat-connect copper pipe systems. This fitting uses a C x C connection style, meaning both ends accept standard copper pipe via soldering. Plumbers and pipefitters rely on unions like this one when they need a joint that can be taken apart without cutting the pipe. That makes it a go-to choice for maintenance access points, equipment hookups, and any run of copper pipe that may need to be serviced in the future. The wrot copper construction means the fitting is made from wrought copper, which is worked and shaped for tighter grain structure and higher strength compared to cast fittings. Wrot copper unions meet ASTM B88 pipe compatibility standards and are widely accepted in residential, commercial, and light industrial plumbing applications. The 1/2 inch size fits the most common small-diameter copper water lines found in residential supply systems, fixture connections, and HVAC hydronic lines. The three-piece union design includes two end pieces and a center nut. Each end is soldered onto the pipe, and the nut draws the two halves together to form a leak-free seal. When the joint needs to be broken, simply unthread the nut. No cutting, no damage to the pipe. Matco-Norca is a well-established supplier of copper and brass fittings for the plumbing trade. Their fittings are built to standard dimensions and are compatible with copper tubing from most major manufacturers. This union is a dependable, code-compliant solution for copper sweat applications.

• 1/2 inch C x C connection on both ends for standard sweat soldering onto copper pipe
• Wrot copper construction provides high strength and dense grain structure for long-term reliability
• Three-piece union design allows the joint to be disassembled without cutting pipe, ideal for service access points
