DELPHI FITTINGS
Product Overview
The Delphi Fittings Part 2701-SS is a 37° JIC Bulkhead 90° Elbow, engineered to create a right-angle connection for hydraulic lines passing through panels, bulkheads, or equipment walls. This fitting features male JIC 37° flare connections on both ends and includes a locknut for secure mounting to the panel. It allows for a 90-degree change in direction immediately at the panel pass-through point, optimizing line routing in confined spaces. Constructed from high-quality 316 stainless steel with the corrosion-resistant stainless steel surface for corrosion resistance, the Part 2701-SS ensures a durable and leak-resistant connection conforming to SAE J514 standards.
Key Features & Specifications

Specific Applications & Hydraulic Circuit Routing
Part 2701-SS stainless steel fittings provide reliable fluid power conveyance in demanding mobile, marine, and process circuits:
- Marine, Subsea & Offshore Systems: Widely deployed on offshore drilling rigs, subsea control umbilicals, ROV hydraulic manifolds, and shipboard deck equipment exposed to constant saltwater spray.
- Chemical & Petrochemical Processing: Reliable fluid conveyance for corrosive process chemicals, hydrocarbon refining sampling lines, and chemical injection skids.
- Food, Beverage & Pharmaceutical Processing: Sanitary clean-in-place (CIP) hydraulic actuation and washdown food packaging lines where strict hygiene and rust prevention are mandated.
- High-Purity Gas & Severe Environment Fluid Power: Ensures zero corrosion degradation in semiconductor gas delivery lines, pulp and paper chlorine wash lines, and heavy coastal machinery.
Installation & Assembly Guidance
- Apply Anti-Seize Lubricant: Stainless steel threads are inherently susceptible to galling. Always apply a thin, uniform coating of stainless-compatible anti-seize or PTFE thread paste prior to assembly.
- Inspect Threads & Sealing Faces: Check that threads and sealing seats (flares, cones, or O-ring grooves) are completely clean, deburred, and free of microscopic grit or tooling marks.
- Hand-Start Carefully: Engage threads by hand for at least 2-3 full turns to verify smooth, concentric alignment and avoid cross-threading.
- Torque to Engineering Limits: Use calibrated wrenches to torque the connection to the specified torque value. Avoid excessive torque, which can accelerate thread galling or distort sealing faces.
Why Source Part 2701-SS from Delphi Fittings?
- Multi-Axis CNC Machining from 316 Barstock: Every Part 2701-SS is precision turned and milled from certified 316/316L stainless steel bar, ensuring exceptional dimensional repeatability and smooth surface finish.
- ASTM A967 Chemical Passivation: All stainless parts undergo validated nitric/citric acid passivation, eliminating surface free iron and forming an ultra-durable chromium oxide passive protective layer.
- 100% Go/No-Go Gauge & Optical Inspection: Threads are strictly verified using calibrated class 2A/2B and 6g/6H thread gauges and optical comparator vision inspection.
- Factory Direct OEM & Distributor Container Pricing: Direct factory supply with complete material test reports (MTR), full traceability, and custom private-label export packaging.
