DELPHI FITTINGS
Part Number: 6400-SS
37° JIC Male x SAE ORB Male Adapter (Stainless Steel)
Product Overview
The Delphi Fittings Part 6400-SS is a high-quality straight adapter manufactured from premium stainless steel (typically Grade 316 SS). It is expertly designed to create a reliable connection between a female JIC (37° flare) swivel fitting or flared tube and a female SAE O-Ring Boss (ORB) port. This adapter features a male JIC 37° flare on one end and a male SAE O-Ring Boss thread with an O-ring groove on the other. The inherent properties of stainless steel provide excellent corrosion resistance, making this adapter an ideal choice for demanding environments such as marine applications, chemical processing industries, or food and beverage equipment where hygiene and resistance to aggressive media are paramount.
Key Features & Specifications
| Material | High-Grade Stainless Steel (Typically 316 SS for superior corrosion resistance) |
|---|---|
| End 1 Configuration | Male 37° JIC Flare (conforming to SAE J514 / ISO 8434-2) |
| End 2 Configuration | Male SAE O-Ring Boss (ORB) (conforming to SAE J1926-1 / ISO 11926-1) |
| Body Style | Straight Adapter with hexagonal (hex) body for secure wrench tightening. |
| Sealing Mechanism | JIC End: Achieves a metal-to-metal seal on the 37° flare cone. ORB End: Utilizes an elastomeric O-ring (typically Viton® for stainless steel applications) which seals against the chamfered boss of the female ORB port, providing excellent leak prevention. |
| Corrosion Protection | Inherent to stainless steel material; may be passivated to enhance corrosion resistance further. |
| Primary Function | To provide a straight, leak-proof connection between a female JIC fitting or flared tube and a female SAE ORB port, specifically in applications requiring the superior corrosion resistance of stainless steel. |
| Working Pressure | Suitable for high-pressure hydraulic systems. Specific pressure ratings depend on the size of the adapter and the application conditions. |
| O-Ring Material (for ORB end) | Viton® (FKM) is highly recommended for stainless steel applications due to its excellent temperature and chemical compatibility. O-ring is typically supplied with the fitting. |
Commonly Available Sizes (Part #6400-SS Series)

Note: Each ORB male end is supplied with an appropriate O-ring (Viton® recommended for stainless steel applications). For unlisted size combinations, specific material grade requirements (e.g., 316L), or other custom needs, please contact our sales team.
Applications
The Part 6400-SS Stainless Steel adapter is ideal for:
- Connecting JIC hydraulic lines (hoses or tubes with female JIC swivel ends) to ORB ports on critical components such as pumps, valves, cylinders, and manifolds, especially in corrosive or high-purity environments.
- Marine and offshore hydraulic systems exposed to saltwater and harsh weather conditions.
- Chemical processing plants where resistance to aggressive chemicals is necessary.
- Food and beverage industry equipment requiring hygienic, non-corrosive connections and frequent washdowns.
- Pharmaceutical manufacturing and biotech applications demanding high cleanliness and material inertness.
- Any hydraulic system where the integrity of the connection and resistance to corrosion are paramount, and the superior performance of stainless steel is required.
Installation & Usage Guidelines
- Ensure all JIC flare surfaces, ORB threads, the O-ring groove on the ORB end, and mating port surfaces are impeccably clean, undamaged, and free from any particulate matter or contaminants.
- Verify that the O-ring material (Viton® is recommended for stainless steel and aggressive media) is appropriate for the specific application's fluid, temperature, and pressure. Ensure the O-ring is correctly lubricated with a system-compatible fluid or O-ring lubricant.
- Carefully install the lubricated O-ring onto the ORB male end of the adapter, ensuring it is properly seated in the groove without being twisted or pinched.
- Thread the ORB male end of the adapter into the female ORB port by hand until the O-ring makes initial contact with the port's chamfer and the fitting shoulder seats. Then, use a wrench on the hex body to tighten the fitting to the manufacturer's recommended torque specification for the ORB size and stainless steel material.
- Connect the male JIC flare end of the adapter to a mating female JIC swivel fitting. Ensure the 37° flare surfaces align correctly. Lightly lubricate the threads of the JIC swivel nut (not the flare sealing surface) with a system-compatible fluid. Tighten the JIC swivel nut to the recommended torque for the specific JIC size.
- Always use backup wrenches on the adapter hex and mating components where appropriate to prevent distortion or damage during tightening. For stainless steel fittings, applying a suitable thread lubricant (anti-seize compound compatible with stainless steel) to the ORB threads and JIC swivel nut threads is crucial to prevent galling during assembly.
