What Is A Wye Fitting

A fitting with three openings, a wye is used to create branch lines. It is a type of tee fitting which has the side inlet pipe entering at a 45° angle, or an angle other than 90 degrees. A standard wye is a “Y” shaped fitting which allows one pipe to be joined to another at a 45 degree angle.
