Wyes

Wyes are special. Substituting a pipe with a lateral welded-on outlet may be more economical and offer quicker shipment. See Special Fittings or contact AMERICAN. A tee with a 45° bend may also offer quicker shipment.

Numerals on cuts indicate standard order of specifying size of fitting.

The center-to-face designations “M”, “N” and “P” are used for straight size wyes as well as reducing wyes; however, in Standard Dimensions the letters “D” and “E” are used for specifying center-to-face dimensions for straight size wyes.
