DELPHI FITTINGS
Part Number: 6501
NPTF Male Pipe x 37° JIC Female Swivel 90° Elbow
Product Overview
The Delphi Fittings Part 6501 is a 90° adapter elbow designed to connect a male NPTF (National Pipe Taper Fuel / Dryseal) pipe or fitting to a JIC (Joint Industry Council) 37° flare connection, typically a female JIC swivel nut on a hose or tube. This fitting features a male NPTF pipe thread on one end and a female JIC 37° swivel nut on the other, facilitating a right-angle transition between these two common hydraulic thread types. The JIC swivel end allows for easy alignment and installation without inducing twist in the hose, crucial for preventing hose damage and ensuring a proper seal. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 6501 ensures a durable and leak-resistant connection in demanding hydraulic systems.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Male NPTF Pipe (Dryseal) (per ANSI B1.20.3 / SAE J476) |
| End 2 Configuration | Female 37° JIC Swivel Nut (per SAE J514 / ISO 8434-2) |
| Angle | 90 Degrees |
| Body Style | Elbow Adapter with hexagonal features for secure wrench tightening. |
| Sealing Mechanism | NPTF End: Metal-to-metal seal on the tapered Dryseal threads when mated with a female NPTF port (or standard NPT port, typically requiring sealant). JIC End: Metal-to-metal seal on the 37° cone seat inside the female swivel end when connected to a mating male JIC flare fitting or flared tube. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability. |
| Primary Function | To connect a male NPTF pipe or fitting to a female JIC swivel hose or tube end at a 90° angle, allowing for the adaptation of different thread types and a directional change in the hydraulic line. |
| Working Pressure | Suitable for high-pressure hydraulic applications. Specific pressure ratings vary by size and should be confirmed for the intended application. |

Applications
The Part 6501 NPTF Male to JIC Female Swivel 90° Elbow is ideal for:
- Connecting components with male NPTF threaded ports (such as pumps, valves, cylinders, or manifolds) to hydraulic hoses or tubes that are terminated with female JIC swivel ends, especially where a 90-degree change in line direction is required.
- Integrating NPTF standard components into hydraulic systems that primarily use JIC flare connections, or vice-versa, while accommodating a right-angle turn.
- Installations in confined spaces where the swivel feature of the JIC end allows for easier alignment and tightening of the connection without twisting the hose assembly.
- Commonly used in mobile equipment (e.g., construction, agriculture), industrial machinery, manufacturing equipment, and general fluid power systems requiring versatile and reliable angled connections.
Installation & Usage Guidelines
- Ensure all threads (male NPTF) and sealing surfaces (JIC 37° cone seat in the female swivel) are clean, undamaged, and free of any contaminants or debris before assembly.
- For the male NPTF end: Apply a compatible pipe thread sealant (such as PTFE tape or liquid sealant) to the male NPTF threads, especially if mating with a standard NPT female port or for high-pressure applications to ensure a leak-proof seal. Thread the NPTF end into the mating female NPTF port and tighten to the recommended torque or industry best practice, achieving the desired orientation of the elbow.
- For the female JIC swivel end: Align the elbow with the mating male JIC fitting or flared tube end. The swivel nut allows the elbow body to be held stationary in the correct 90-degree orientation while the nut is tightened independently. Hand-tighten the swivel nut, then use a wrench to tighten to the recommended torque for the specific JIC size. It's good practice to apply a light coat of system-compatible lubricant to the threads of the swivel nut (not the sealing cone) to ensure smooth tightening.
- Use backup wrenches on the elbow body and the mating components as necessary during tightening to prevent distortion or damage to the fittings or connected lines.
Why Choose Delphi Fittings Part 6501?
- Versatile Inter-Standard Connection: Effectively adapts NPTF male connections to JIC female swivel connections at a crucial 90° angle, bridging two common hydraulic standards.
- Simplified Installation: The JIC female swivel end facilitates easy alignment and stress-free tightening, preventing hose twist and simplifying assembly in complex routings.
