Frequently Asked Questions about Stainless Steel Double Ferrule Female Bulkhead Union

Answers to the questions buyers, piping engineers, and procurement teams most often ask before sourcing Stainless Steel Double Ferrule Female Bulkhead Union from Pioneer Industries.

A Stainless Steel Double Ferrule Female Bulkhead Union is a specialized through-panel coupling designed to pass tubing lines through instrument enclosures, control panels, or bulkheads. It features an extended cylindrical threaded body with a heavy-duty locking nut and double ferrule tube sockets on both ends, allowing two tubing runs of equal diameter to connect securely across a partition wall without leaks or mechanical strain.
Standard Pioneer Bulkhead Unions accommodate panel wall thicknesses ranging from 0.06″ (1.5 mm) up to 0.50″ (12.7 mm). For heavily insulated enclosures or thick offshore firewall partitions, custom extended bulkhead barrels can be fabricated upon request.
By clamping rigidly against the panel using its machined locknut, the bulkhead union acts as a solid mechanical anchor. High-frequency line vibration and thermal expansion forces generated by outside pumps or compressors are absorbed by the panel structure rather than being transferred to sensitive instruments inside the cabinet.
Pioneer SS 316/316L Bulkhead Unions are rated up to 10,000 PSI (690 bar) for sizes up to 1/2″ (12 mm) and up to 6,000 PSI for larger sizes up to 1″, engineered in accordance with ASME B31.3 with a 4:1 safety factor.
Yes. For weather-tight (IP66/NEMA 4X) or positive-pressure purged analyzer shelters, Pioneer provides optional Viton or PTFE bulkhead sealing washers that seal against the panel cutout, preventing water, dust, and corrosive fumes from entering.
Yes. Either the internal or external tube connection can be disassembled, inspected, or serviced without loosening the panel locknut or disturbing the opposite tube connection.
Drill a hole matching Pioneer's specified drill size. Remove the locknut and one coupling nut, pass the bulkhead body through the panel, re-thread and wrench-tighten the locknut firmly against the panel surface. Then insert tubing into both ends and tighten coupling nuts 1-1/4 turns from finger-tight.
Coupling nut internal threads feature dry-film silver electroplating to reduce makeup torque by 40% and eliminate galling. Bulkhead locknut threads are precision-machined with smooth flanks for easy field adjustment.
Yes. Pioneer supplies bulkhead unions in solution-annealed SS 316/316L, Super Duplex 2507, and Monel 400 with hardness strictly verified under 22 HRC per NACE MR0175 / ISO 15156.
Shipments include authentic EN 10204 Type 3.1 Inspection Certificates with heat chemical analysis, mechanical tensile and yield data, hardness results, hydrostatic test reports, and 100% Positive Material Identification (PMI) spectrometer verification.
