About This Product

Securely connect copper tubing with this 3/4 in. press x 1 in. female bronze union tailpiece. This zero-lead fitting allows easy disconnection without cutting or damaging existing pipes. Press connections make installation fast and efficient, eliminating the need for calibration, open flame, or heavy equipment. Installation is completed in four simple steps: cut the copper tube to length, remove burrs and surface imperfections, measure and mark the insertion depth, then use a press tool to create a secure connection. Built-in leak detection helps identify unpressed connections during pressure testing, ensuring proper installation the first time. Approved to major plumbing and mechanical codes and available in hundreds of fitting configurations, these press bronze unions are designed to handle a wide range of plumbing and HVAC applications.
