CNC machining delivers micron precision and tight tolerances for complex geometry.
Optimized for mass production, high-volume machining utilizes advanced automation and process control to ensure consistent quality, tight tolerances, and superior cost efficiency at scale.
Designed for precision-driven applications, low-volume machining supports prototype development and limited production runs with high accuracy, rapid iteration, and reduced tooling requirements.
These fittings also serve to isolate different pressure zones and are often engineered for vacuum compatibility or high burst pressure ratings, depending on system requirements.
Localized stress around bulkhead openings often leads to mechanical failure, particularly under cyclic loading or thermal expansion. Precision-machined bulkhead fittings with full thread engagement, step-down shoulders, and support flanges mitigate stress risers and distribute mechanical loads over the entire panel contact area. This design approach prevents deflection of the mounting surface, which can otherwise propagate fatigue cracks or reduce sealing efficiency.
Certain system architectures require complete electrical isolation across a mechanical pass-through, especially in EMI-sensitive or high-voltage assemblies. Non-conductive bulkhead fittings incorporate high-dielectric constant polymer insulators or ceramic inserts with low leakage current coefficients. These components ensure controlled impedance, eliminate parasitic capacitance, and allow safe routing of signal or power conductors without compromising enclosure shielding or introducing unintended ground loops.

Transfers pressurized hydraulic fluid through fuselage walls while maintaining structural integrity and preventing fluid leakage under vibration loads.
Enables sealed fluid and signal transmission across pressure boundaries in ROVs and underwater distribution units at extreme depths.
Provides leak-tight connections for low-temperature liquids across insulated vacuum-jacketed enclosures with matched thermal expansion properties.
Delivers chemical-grade fluids between containment zones, meeting ultra-high purity standards and resisting corrosive acid-base media.
Maintains gas-tight isolation of hydrogen and air feed lines through metallic bulkhead surfaces in high-efficiency stack assemblies.
Facilitates secure transfer of coolant across shielded containment walls under high radiation and elevated pressure-temperature conditions.
Media transmission through fittings under dynamic conditions can induce hydraulic shock or vibrational resonance, particularly in long-run tubing or piping systems. High-density bulkhead fittings with tuned natural frequencies and reinforced hex bases prevent amplification of mechanical oscillations. These components are often coupled with dampening bushings or ferrule interfaces that absorb residual motion, maintaining system calibration and preventing connector loosening.
Certain applications involve strict separation of dissimilar fluids or gases across multiple zones. Dual-channel or coaxial bulkhead designs enable isolated flow paths within a single structural interface, maintaining independent sealing boundaries. This architecture is common in analytical instrumentation, chemical processing skids, and fuel cell assemblies, where cross-contamination poses reliability or safety risks.

Frigate designs bulkhead fittings with precision-machined sealing faces and integrated load-bearing shoulders to avoid micro-movement during pressure cycling. Finite element analysis (FEA) is used to validate deformation limits under combined thermal and mechanical loads. Optional anti-vibration locking nuts and elastomer damping washers are offered for dynamic environments. This helps maintain long-term sealing reliability in hydraulic, pneumatic, and subsea applications.
Frigate supplies full material traceability with MTRs (Material Test Reports) aligned to ASTM, EN, or ASME specifications. For aerospace, nuclear, and medical systems, certifications include ISO 10204-3.1 or 3.2 documents and compliance with DFARS or REACH regulations. Dimensional inspection reports and helium leak testing data are available upon request. This ensures every bulkhead fitting meets exacting project validation requirements.
Frigate manufactures fittings in high-performance alloys like Hastelloy C276, Super Duplex, and PTFE-lined stainless steel for aggressive chemical environments. Surface treatments include electropolishing, passivation, and PVD coatings to reduce corrosion initiation points. All wetted surfaces are analyzed for compatibility with specific chemical concentrations and pH ranges. This approach supports long-term deployment in offshore, desalination, and caustic chemical handling systems.
Frigate’s UHP (Ultra High Purity) bulkhead fittings are fabricated in Class 100 clean environments with automated orbital welding and sub-10 µin Ra internal surface finish. Designs eliminate dead volume and crevices to reduce particle entrapment. Fittings are vacuum-bag packaged and certified per SEMI F20, ASME-BPE, or ISO 14644 standards. This ensures contamination-free fluid transfer across isolation panels in wafer processing and wet benches.
Frigate engineers dual-path and coaxial bulkhead fittings that support independent media routing within a single mounting footprint. Each path is sealed with discrete O-ring or welded interfaces to prevent cross-contamination. These are commonly used in fuel cells, cryogenic instrumentation, and aerospace cooling loops. Custom lengths, port terminations, and isolation ratings are configured based on system-specific media, flow, and pressure requirements.
