Copper Coupling 3/4 in. x 3/4 in. Lead Free PSI-300

Utilize the 3/4-inch coupling for reliable extensions and repairs of ASTM B88 and B75 copper tubing. This coupling is designed with an internal stop indentation that halts the pipe halfway through the fitting upon insertion. Its straightforward press connections make the installation process fast and effective. Unlike conventional pipe fittings, there is no requirement for calibration, flame, or heavy tools. Instead, couplings can be installed in just three simple steps: cut the copper tube to the desired length and eliminate any burrs or flaws, measure and mark the depth for fitting, and apply a press tool to secure the coupling for a strong connection. The technology detects unpressed fittings during pressure testing to guarantee correct connections on the first attempt and reduce callbacks. This system is approved by the most codes and standards compared to any other copper press fitting system (including IPC, UPC, and NSF), and offers over 400 different fitting configurations to accommodate nearly any plumbing or HVAC project, making pipe fittings the preferred choice for professionals worldwide.
