Designed for fluid distribution manifolds requiring a straight-through run from tubing into a female pipe thread with an orthogonal 90-degree branch, Pioneer Brass Double Ferrule Male Run Tees provide high-pressure sealing up to 5,000 PSI.
The Brass Double Ferrule Male Run Tee is a three-way fitting featuring an in-line run consisting of one compression tube port and one male pipe thread (NPT or BSPT), along with an orthogonal 90-degree compression tube branch. This configuration allows a continuous tubing stream to feed directly into a female-threaded component while branching off to a secondary line.
Forged from dense, high-strength brass alloy (ASTM B283 CW617N), Pioneer Male Run Tees resist thread deformation and mechanical twisting under severe operational torque, while twin-ferrule mechanical grip guarantees zero leakage across both tube ports.
Exported globally by Pioneer Industries Mumbai to pneumatic panel fabricators, instrumentation engineers, and mobile hydraulic equipment manufacturers.
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.

Each run tee is CNC-machined from precision brass forgings, ensuring uniform wall thickness around the pipe thread and high burst strength under dynamic hydraulic shock.
The two compression ports incorporate hardened back ferrules with burnished colleting surfaces, isolating tubing from wrench rotational forces during assembly.
Metric sizes 6 mm to 25 mm OD (MPMRT Series) and fractional sizes 1/8" to 1" OD (IPMRT Series) with male pipe threads from 1/8" to 1" NPT/BSPT.

Expert engineering insights and technical guidance regarding swaging mechanics, pressure thresholds, tubing compatibility, and installation protocols for Brass Double Ferrule Male Run Tee.
A Brass Double Ferrule Male Run Tee is a 3-way fitting where the in-line straight 'run' consists of one double-ferrule tube connection and one male pipe thread, while the 90-degree 'branch' is a double-ferrule tube connection.
In a male run tee, the male pipe thread is on the straight in-line axis (run), whereas in a male branch tee, the male pipe thread is on the 90-degree perpendicular leg (branch).
Metric Series MPMRT covers 6mm to 25mm tube OD, and Fractional Series IPMRT covers 1/8″ to 1″ tube OD with male NPT/BSPT threads from 1/8″ to 1″.
Rated up to 5,000 PSI (345 Bar) for sizes 1/8″ to 1/4″ and up to 3,200 PSI for 1/2″ size, adhering to ASME B31.3 instrumentation codes.
Hot-forged brass bodies conforming to ASTM B283 CW617N / C37700 or bar stock ASTM B16 Alloy C36000.
Apply high-grade PTFE thread tape or liquid anaerobic pipe sealant to the male threads, threading into the female port and torquing to proper alignment.
Insert tubing squarely into each ferrule port until seated, finger-tighten the nuts, and advance 1-1/4 turns with a wrench.
Yes. Both tube ports can be remade multiple times by retightening approx. 1/12 to 1/6 turn beyond finger-tight.
Yes, precision twin-ferrule mechanical swaging ensures vacuum sealing down to 1 × 10⁻⁹ mbar·l/s.
