3/4-inch cast bronze wye trap

The Nibco 749 is a 45-degree wye trap made from cast bronze for plumbing drainage systems. It fits 3/4-inch tube with C x C x C sweat connections and meets ASME B 16.18 standards. The fitting suits installers who need a durable branch connection in residential or light commercial pipework. It is not intended for systems requiring larger diameter branches or different connection types such as threaded or press-fit joints.

Sustained pressure and temperature performance

The casting withstands a maximum working pressure of 466 psi at 200 degrees Fahrenheit and operates across a temperature range of -20 to 400 degrees Fahrenheit. Bronze construction resists corrosion and deformation during continuous hot-water circulation or thermal cycling. The fitting is not designed for pressures above the rated limit or for applications involving aggressive chemical exposure beyond typical potable water conditions.
