Engineered for direct connection from process tubing across cabinet bulkheads into female threaded valves, manifolds, and regulators, Pioneer Industries Brass Double Ferrule Bulkhead Male Connectors feature heavy-duty mounting jam nuts and pressure ratings up to 5,000 PSI.
The Brass Double Ferrule Bulkhead Male Connector combines a panel pass-through mounting barrel with a male NPT, BSPT, or BSPP threaded stud on one side and a double ferrule tube connection on the other. It is specifically engineered to route process tubing through panel bulkheads directly into female-threaded components such as needle valves, regulators, and pneumatic manifolds.
By integrating panel mounting with a male pipe stud, this fitting eliminates intermediary nipple adapters, lowering installation costs, reducing cabinet depth requirements, and enhancing overall system structural rigidity.
Manufactured by Pioneer Industries Mumbai, these bulkhead male connectors are deployed worldwide in automated skid packages, analyzer panels, and marine machinery.
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 Bulkhead Male Connector.
A Brass Double Ferrule Bulkhead Male Connector is an engineered fitting that passes through a panel or enclosure wall, featuring an external bulkhead mounting thread with jam nuts, a male pipe threaded end (NPT/BSPP) on one side, and a double ferrule compression tube socket on the other.
It allows tubing on the outside of a cabinet to connect directly into female-threaded components (such as valves, regulators, or manifolds) mounted on or near the inside panel surface, eliminating external nipples and female unions.
Standard sizes accommodate panel walls from 1.5 mm up to 12.7 mm (1/2″) thick. Custom extended barrels can be supplied for thicker insulated partitions.
Pioneer manufactures male threads in NPT (ASME B1.20.1), BSPT (ISO 7), and BSPP (ISO 228) from 1/8″ to 1″ nominal pipe size.
Depending on tube size and thread specification, working pressures range from vacuum up to 5,000 PSI (345 Bar), meeting ASME B31.3 process piping design rules.
Machined from ASTM B16 Alloy C36000 / IS 319 Grade 1 extruded brass bar stock, providing high mechanical strength, excellent corrosion resistance, and precision thread integrity.
Yes. It connects directly to seamless copper and brass tubing. For nylon or polyurethane tubes, Pioneer brass tube inserts must be used inside the tube end.
Depending on thread diameter, recommended jam nut torque ranges from 15 to 45 Nm to ensure rigid, vibration-proof panel clamping without distorting the fitting barrel.
Yes, certified for helium leak rates below 1 × 10⁻⁹ mbar·l/s, ensuring zero emission in critical gas and fluid applications.
Every export consignment includes EN 10204 Type 3.1 inspection certification with chemical composition, mechanical properties, and hydrostatic test data.
