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

Utilize the 3/4-inch Coupling without a Stop to create reliable extensions and repairs for ASTM B88 and B75 copper tubing. This coupling features no internal stop, enabling installers to easily fit it into narrow spaces. With its straightforward press connections, the installation process is both fast and effective. In contrast to conventional pipe fittings, there's no requirement for calibration, flame, or heavy machinery. Instead, installing couplings is accomplished in just three simple steps: cut the copper tube to the desired length and eliminate any burrs or defects, measure and indicate the fitting depth, and employ a press tool to secure the coupling for a reliable connection. The technology detects unpressed fittings during pressure tests, ensuring correct connections on the first attempt and reducing callbacks. Approved by more codes and standards than any other copper press fitting system (including IPC, UPC, and NSF), and offering over 400 various fitting configurations to accommodate almost any plumbing or HVAC project, pipe fittings are the preferred choice for professionals worldwide.
