DELPHI FITTINGS
Part Number: 6402-SS
SAE ORB Male x 37° JIC Female Swivel Nut Adapter (Stainless Steel)
Product Overview
The Delphi Fittings Part 6402-SS is a straight adapter, meticulously manufactured from premium stainless steel (typically Grade 316 SS), designed to provide a reliable connection between a male SAE O-Ring Boss (ORB) port and a JIC (Joint Industry Council) 37° flare connection. This adapter features a male SAE O-Ring Boss thread with an O-ring groove on one end, and a female JIC 37° swivel nut on the other, commonly used for connecting to hydraulic hose assemblies or flared tubes. The stainless steel construction ensures exceptional corrosion resistance, making the 6402-SS ideal for demanding applications in marine environments, chemical processing, food and beverage industries, or any system where hygiene and resistance to aggressive media are critical. The JIC swivel nut facilitates easy installation by allowing the nut to be tightened without twisting the hose or fitting body.
Key Features & Specifications
| Material | High-Grade Stainless Steel (Typically 316 SS for superior corrosion resistance) |
|---|---|
| End 1 Configuration | Male SAE O-Ring Boss (ORB) (conforming to SAE J1926-1 / ISO 11926-1) |
| End 2 Configuration | Female 37° JIC Swivel Nut (conforming to SAE J514 / ISO 8434-2) |
| Body Style | Straight Adapter with hexagonal (hex) body for secure wrench engagement. |
| Sealing Mechanism | ORB End: Utilizes an elastomeric O-ring (Viton® recommended for stainless steel) which seals against the chamfered boss of the female ORB port, providing a highly reliable, leak-proof seal. JIC End: Achieves a metal-to-metal seal on the 37° cone seat located inside the female swivel end when connected to a mating male JIC 37° flare fitting or a correctly flared tube end. |
| Corrosion Protection | Inherent to the stainless steel material; may be passivated to further enhance surface integrity and corrosion resistance. |
| Primary Function | To establish a straight, leak-proof connection from a male SAE ORB port to a female JIC swivel fitting or hose end, offering the superior durability and 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 operational conditions. |
| O-Ring Material (for ORB end) | Viton® (FKM) is strongly recommended for stainless steel applications to ensure compatibility with aggressive fluids and wider temperature ranges. O-ring is typically supplied with the fitting. |

Applications
The Part 6402-SS Stainless Steel adapter is the preferred choice for:
- Connecting components with male ORB ports (such as pumps, valves, cylinders, and manifolds) to hydraulic hoses or tubes terminated with female JIC swivel ends, particularly in environments where corrosion resistance is critical.
- Interfacing stainless steel ORB ported components with stainless steel JIC hose assemblies to maintain material integrity and prevent galvanic corrosion.
- Use in marine and offshore hydraulic systems, chemical processing plants, food and beverage manufacturing equipment, pharmaceutical production lines, and other industries requiring high levels of cleanliness, resistance to aggressive fluids, or frequent washdowns.
- Applications where the ease of installation provided by the JIC swivel nut is beneficial, especially in tight or complex assemblies.
Installation & Usage Guidelines
- Ensure all ORB threads, the O-ring groove, the JIC swivel nut threads, and all mating sealing surfaces (ORB port chamfer, JIC male flare) are meticulously clean, undamaged, and free from any particulate matter or contaminants.
- Verify that the O-ring material (Viton® is recommended for stainless steel applications) is correct for the specific application's fluid, temperature, and pressure. Ensure the O-ring is correctly lubricated with a system-compatible fluid or an appropriate O-ring lubricant.
- Carefully install the lubricated O-ring onto the ORB male end of the adapter, ensuring it is properly seated in its groove without being twisted, cut, 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, using a wrench on the hex body, tighten the fitting to the manufacturer's recommended torque specification for the ORB size and stainless steel material.
- Connect the female JIC swivel end of the adapter to a mating male JIC fitting or a correctly flared tube end. The swivel nut allows the adapter body to be held stationary while the nut is tightened independently to the recommended torque for the specific JIC size. A light application of system-compatible lubricant on the JIC swivel nut threads (not the sealing cone) can aid in smooth tightening.
- Always use appropriate backup wrenches on the adapter hex and mating components during tightening to prevent distortion or damage. For stainless steel fittings, using a thread lubricant or anti-seize compound (compatible with stainless steel) on both the ORB threads and JIC swivel nut threads is crucial to prevent galling during assembly.
