Securely connect tubes with the ProPress copper 45° elbow. Designed for use with ASTM B88 and B75 copper tubing, elbows allow for more convenient connection options in tight situations. Press connections make installing this 45° elbow quick and efficient. Unlike traditional pipe fittings, there's no need for calibration, flame or heavy equipment. Instead, Viega ProPress elbows install in just four easy steps: cut the copper tube to length, remove any burrs and surface imperfections, measure and mark the fitting insertion depth, and use a press tool to connect the Viega ProPress 45° elbow for a secure connection. Smart Connect technology identifies unpressed connections during pressure testing to ensure proper connections the first time and eliminate callbacks. Approved to the most codes and standards of any other copper press fitting system (IPC, UPC and NSF included), and with more than 4 different fitting configurations to suit virtually any type of plumbing or HVAC job, Viega ProPress elbows are the top choice of professionals around the globe.
