Grooved reducing tee, named for its T-shaped configuration, has a branch outlet with a different size from the main outlet. Each end of the tee has a groove, allowing it to be quickly and easily connected to the pipeline using couplings or fittings.
Grooved reducing tee is suitable for piping systems in industries such as petroleum, chemical, oil, natural gas, and urban construction, like heating pipeline systems, drainage and water supply systems, and more.
Connects pipe, provides changes in direction, and adapts to sizes or components.
