The foundational fitting of instrumentation piping, Pioneer Industries Brass Double Ferrule Male Connectors couple process tubing directly to female-threaded valves, manifolds, and regulators up to 5,000 PSI.
The Brass Double Ferrule Male Connector is the most widely utilized tube fitting in industrial instrumentation, providing a straight transition from a twin-ferrule compression tube socket to a male NPT, BSPT, or BSPP pipe thread. It allows tubing to connect directly into female-threaded pumps, valves, manifolds, and pressure transmitters.
Pioneer Male Connectors feature precision-honed internal 20-degree camming tapers and cleanly cut male pipe threads. When tightened, the front ferrule creates a primary fluid seal against the body taper, while the back ferrule grips the tube OD to isolate vibration.
Manufactured by Pioneer Industries Mumbai, these male connectors are exported globally to automation OEMs, analytical system builders, and petrochemical refineries in over 85 countries.
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 Connector.
A Brass Double Ferrule Male Connector is a straight fitting featuring a twin-ferrule compression tube socket on one end and a male pipe threaded stud (NPT, BSPP, or BSPT) on the other, designed to connect tubing directly into a female pipe thread.
Pioneer manufactures male threads in NPT (ASME B1.20.1), BSPP (ISO 228), and BSPT (ISO 7) in sizes from 1/16″ to 1″ nominal.
Pressures range up to 5,000 PSI (345 Bar) for sizes 1/16″ to 1/4″ and up to 3,200 PSI for 1/2″ size, with a 4:1 safety factor under ASME B31.3.
Manufactured from extruded brass bar stock conforming to ASTM B16 Alloy C36000, IS 319 Grade 1, and EN 12164 CW614N.
Screw the male pipe thread into the female port using approved PTFE sealant. Then insert the tube squarely into the ferrule socket, finger-tighten the nut, and wrench-tighten 1-1/4 turns.
Yes. The compression joint can be disassembled and remade repeatedly by tightening the nut approx. 1/12 to 1/6 turn past snug.
Yes. Fully compatible with seamless copper (ASTM B75/B88) and brass (ASTM B135). For plastic tubes, brass tube inserts are required.
Yes, certified helium leak tight (< 1 × 10⁻⁹ mbar·l/s) and suitable for vacuum lines down to -750 mmHg.
-200°C to +200°C (-328°F to +392°F) continuous operating envelope.
