Designed to adapt double ferrule tube fitting ports into male NPT, BSPT, or BSPP pipe threads, Pioneer Industries Brass Double Ferrule Male Adapters eliminate pipe thread alignment stress up to 5,000 PSI.
The Brass Double Ferrule Male Adapter features a precision-machined smooth tube stub on one end and a male NPT, BSPP, or BSPT threaded pipe connection on the other. It is inserted directly into any standard twin-ferrule fitting port (such as a tee, elbow, or valve) to provide a male pipe connection.
Using an adapter stub rather than a standard pipe nipple allows 360-degree rotational alignment before tightening the compression nut. This completely eliminates alignment stress on pipe threads and drastically simplifies complex piping hookups.
Manufactured by Pioneer Industries Mumbai, our Brass Male Adapters are exported globally to instrument panel builders, power generation plants, and HVAC 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.

Expert engineering insights and technical guidance regarding swaging mechanics, pressure thresholds, tubing compatibility, and installation protocols for Brass Double Ferrule Male Adapter.
A Brass Double Ferrule Male Adapter features a smooth machined tube stub on one end and a male threaded pipe stud (NPT, BSPP, or BSPT) on the other, designed to insert into a double ferrule fitting socket to provide a male pipe thread.
A male adapter allows 360-degree rotational orientation. You screw the male thread into the female port first, then insert the tube stub into the mating fitting and align it at any angle before tightening the nut, eliminating thread over-tightening.
Metric Series MPMA covers 3mm to 25mm tube stubs with 1/8″ to 1″ male threads. Fractional Series IPMA covers 1/8″ to 1″ tube stubs with 1/8″ to 1″ male threads.
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 under ASME B31.3 specifications.
Machined from extruded brass bar stock conforming to ASTM B16 Alloy C36000 and IS 319 Grade 1.
Thread the male pipe end into the female port using approved PTFE sealant. Then insert the tube stub into the compression fitting body, finger-tighten, and wrench-tighten 1-1/4 turns.
Yes. Once the ferrules are swaged onto the adapter stub, the connection can be remade repeatedly like any swaged tube.
Yes, certified helium leak tight (< 1 × 10⁻⁹ mbar·l/s) down to -750 mmHg vacuum.
Available in NPT (ASME B1.20.1), BSPT (ISO 7), and BSPP (ISO 228) from 1/8″ to 1″ nominal pipe size.
