316L Stainless Steel Compression fitting internal thread branch tee

The 316L Stainless Steel Compression fitting internal thread branch tee is a pipe fitting used to connect three pipes. Its structure is typically a tee design, with the main pipe being a straight connection and the branch pipe end using an internal thread interface, allowing direct connection to external threaded fittings or instrumentation equipment. The tee body is manufactured using integral forging or precision machining processes, resulting in a smooth and uniform internal flow channel, which helps reduce fluid resistance and pressure loss. The main structure includes two straight ends and one internally threaded branch end. This product is suitable for pipe diameters from 1/8" to 2" (3mm to 50mm), with working pressures up to 6000 psi. Thread standards include NPT, BSPT, BSPP, and ISO series. The seal is a metal hard seal, and it can transport gases, liquids, steam, corrosive fluids, and high-purity media.
