T-fitting for use with different diameter pipes

摘要

A T-fitting for use with pipes of different diameter sizes includes a generally T-shaped hollow body defining a central flow transition passageway, and three spaced-apart pipe-connecting hollow ends formed on the body in flow communication with its central flow transition passageway. A pair of the pipe-connecting ends share a common axis and are disposed in opposing relation on the body. Each of the pair of pipe-connecting ends has a pair of tandemly-arranged outer and inner pipe-receiving sections defining respective outer and inner passageways in flow communication with the central passageway. The outer passageway is larger in diameter than the inner passageway, and the respective outer and inner sections have outer and inner shoulders with respective outwardly-facing internal surfaces adapted to abut with ends of pipes of different size diameters when received in the respective passageways. The other pipe-connecting hollow end is disposed generally between and offset from the common axis of the two pipe-connecting ends and has an axis extending in a generally orthogonal relation to the common axis.
