DELPHI FITTINGS
Part Number: 6400L-SS
37° JIC Male x SAE ORB Male Adapter Long (Stainless Steel)
Product Overview
The Delphi Fittings Part 6400L-SS is an extended length version of our standard 6400-SS straight adapter, meticulously manufactured from high-quality stainless steel (typically Grade 316 SS). This adapter is specifically engineered to connect a female JIC (37° flare) swivel fitting or flared tube to a female SAE O-Ring Boss (ORB) port that may be recessed, obstructed, or otherwise difficult to reach with a standard length fitting. It features a male JIC 37° flare on one end and an extended male SAE O-Ring Boss thread with an O-ring groove on the other. The superior corrosion resistance of stainless steel makes this extended adapter essential for challenging installations in marine environments, chemical processing plants, or food and beverage facilities where both durability and reach are critical.
Key Features & Specifications
| Material | High-Grade Stainless Steel (Typically 316 SS for maximum 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) - Extended Length (conforming to SAE J1926-1 / ISO 11926-1 dimensions, with increased reach) |
| Body Style | Straight Adapter with an extended ORB end and hexagonal (hex) body for secure wrench tightening. |
| Sealing Mechanism | JIC End: Achieves a robust metal-to-metal seal on the 37° flare cone. ORB End: Utilizes an elastomeric O-ring (Viton® recommended for stainless steel applications) which seals effectively against the chamfered boss of the female ORB port, providing excellent leak prevention even in recessed locations. |
| Corrosion Protection | Inherent to the stainless steel material; may be passivated to further enhance surface corrosion resistance. |
| Primary Function | To provide a straight, extended connection between a female JIC fitting or flared tube and a difficult-to-access female SAE ORB port, offering superior corrosion resistance for demanding applications. |
| Working Pressure | Suitable for high-pressure hydraulic systems. Specific pressure ratings depend on the size of the adapter and the specific application conditions. |
| O-Ring Material (for ORB end) | Viton® (FKM) is highly recommended for stainless steel fittings due to its excellent temperature and chemical compatibility. O-ring is typically supplied with the fitting. |

The specific extended length can vary by part number; please confirm dimensions for your application. For unlisted size combinations, specific material grade requirements, or custom lengths, please contact our sales team.
Applications
The Part 6400L-SS Stainless Steel extended adapter is particularly useful for:
- Connecting JIC hydraulic lines (hoses or tubes with female JIC swivel ends) to deeply recessed or obstructed ORB ports on components such as pumps, valves, cylinders, and manifolds, especially in corrosive or high-purity environments.
- Installations in marine and offshore hydraulic systems where components are often housed within protective enclosures requiring extended reach fittings.
- Chemical processing plants, food and beverage industry equipment, and pharmaceutical manufacturing where both stainless steel's corrosion resistance and the ability to access hard-to-reach ports are necessary.
- Complex machinery layouts where standard length adapters cannot provide adequate clearance for connection or tooling.
Installation & Usage Guidelines
- Thoroughly clean all JIC flare surfaces, ORB threads, the O-ring groove on the ORB end, and the mating female ORB port surfaces. Ensure they are 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 extended ORB male end of the adapter, ensuring it is properly seated in its groove without being twisted, cut, or pinched.
- Thread the extended 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 (an anti-seize compound compatible with stainless steel) to the ORB threads and JIC swivel nut threads is crucial to prevent galling during assembly, particularly with the extended reach design.
