316L Stainless Steel Compression fitting external thread branch tee

The Male Branch Tee is an essential component in instrumentation piping systems. It features a male threaded port on the side branch, while the two ports on the run are compression tube fittings. This design allows a main tubing line to extend horizontally while simultaneously creating a perpendicular connection to valves, transmitters, or pressure vessels.

Core Product Advantages

Integrated Branching Structure:
This fitting cleverly combines tubing connection with equipment branching. Compared to using multiple adapters, the one-piece forged T-structure significantly reduces potential leak points and provides superior resistance to vibrational fatigue.

Ultimate 316L Corrosion Protection:
Manufactured from ultra-low carbon 316L stainless steel, it excels in resisting pitting and intergranular corrosion. It ensures long-term system stability even in harsh chemical processing, offshore platforms, or hydrogen applications.

Gas-Tight High-Pressure Sealing:
The two run ports utilize classic double-ferrule technology, while the male threaded branch is precision-ground. Whether operating under high pressures up to 6000 psig or handling highly penetrative gases (such as Hydrogen or Helium), it maintains a consistent “zero-leak” performance.

Convenient Installation Flexibility:
The male threaded end supports various international standards (NPT, BSPT, etc.), allowing for easy integration into various equipment ports. Following standard installation procedures, a reliable seal can be achieved with a simple wrench, and the fitting supports multiple disassembly and reassembly cycles.
