Designed for inline transition from process tubing into male pipe threads while providing a 90-degree tubing branch, Pioneer Industries Brass Double Ferrule Female Run Tees deliver leak-tight swaging and vibration resistance up to 5,000 PSI.
The Brass Double Ferrule Female Run Tee features one twin-ferrule compression tube port and one female pipe threaded port on the straight run, plus a second twin-ferrule compression tube port on the 90-degree branch. This specialized configuration is ideal for terminating a tubing line into a male-threaded instrument while continuing a branch tubing circuit.
Pioneer Female Run Tees are hot-forged from high-density brass, providing compact dimensions and reinforced thread walls to resist pipe strain, while double-ferrule mechanical swaging ensures zero leakage under severe pipeline pulsation.
Manufactured by Pioneer Industries Mumbai, these female run tees are exported globally to automation system builders, power plants, and chemical refineries.
Components are precision CNC-machined from premium extruded brass (IS 319 / ASTM B16 / CW614N) with micro-smooth surface finishes. Every production lot undergoes rigorous metallurgical spectrometry, optical CMM dimensional checks, and helium leak detection, accompanied by authentic EN 10204 Type 3.1 Mill Test Certificates.
