Designed for use with ASTM B88 and B75 copper tubing, reducing tees allow for a smooth transition between tubing of different sizes. Press connections make installing this copper tee quick and efficient. Unlike traditional pipe fittings, there's no need for calibration, flame, or heavy equipment. Instead, this tee can be installed 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 tee for a secure connection. smart connect technology identifies unpressed connections during pressure testing to ensure proper connections the first time and eliminate callbacks.
