Use the Viega ProPress 1-1/4 in. Copper Coupling No Stop to make secure extensions and repairs of ASTM B88 and B75 copper tubing. This no-stop coupling allows installers to slide the fitting into position, making it ideal for repairs and installations in tight or confined spaces. Thanks to its easy press connections, installing the coupling is quick and efficient. Unlike traditional pipe fittings, there is no need for calibration, flame or heavy equipment. Instead, Viega ProPress couplings install in just 3 easy steps: cut the copper tube to length and remove any burrs or imperfections, measure and mark the fitting depth, and use a press tool to connect the Viega ProPress coupling for a secure connection. Smart Connect technology identifies unpressed fittings during pressure testing to help ensure proper connections the first time and reduce callbacks. Approved to the most codes and standards of any copper press fitting system (including IPC, UPC and NSF), and with more than 400 fitting configurations available, Viega ProPress fittings are a trusted choice for plumbing and HVAC professionals.
