3/4" x 1/2" piping Tee fitting (Part number M8014). This is a MaxLINE Reducing Tee that is specifically designed for the MaxLINE 3/4" tubing as a main line and reducing the drop line going to the outlet to a 1/2" MaxLine tube. This works great for installations done inside the wall where there is not enough room for the 3/4" tubing and works for many more custom applications. This fitting is made of solid brass and has a double o-ring seal for a no leak connection. Also is has split ring connections for easy disassembly if needed. Rated for 175 psi working pressure.
