DELPHI FITTINGS
Part Number: 6503
NPTF Female Pipe x 37° JIC Female Swivel 90° Elbow
Product Overview
The Delphi Fittings Part 6503 is a 90° adapter elbow designed to create a right-angle connection between a female NPTF (National Pipe Taper Fuel / Dryseal) port and a JIC (Joint Industry Council) 37° flare connection, typically a female JIC swivel nut on a hose or tube assembly. This fitting features a female NPTF pipe thread on one end and a female JIC 37° swivel nut on the other. The JIC swivel end is crucial for allowing easy alignment and installation of the connecting hose or tube without inducing torsional stress, which is particularly beneficial in complex hydraulic routings or tight spaces. Manufactured from high-quality carbon steel and zinc-plated for robust corrosion resistance, the Part 6503 elbow ensures a durable and leak-resistant transition between these two distinct hydraulic connection standards, adhering to SAE J514 and NPTF specifications.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Female 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: Seals with a mating male NPTF pipe fitting (Dryseal). If mating with a standard NPT male fitting, the use of thread sealant is recommended for optimal sealing. 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 and resistance to corrosion. |
| Primary Function | To connect a component with a female NPTF port to a hydraulic hose or tube assembly with a female JIC swivel end, at a 90° angle, thereby accommodating different thread types and facilitating a directional change in the hydraulic line. |
| Working Pressure | Suitable for high-pressure hydraulic applications. Specific pressure ratings vary depending on the size of the fitting. |

Applications
The Part 6503 NPTF Female Pipe x JIC Female Swivel 90° Elbow is widely used in:
- Connecting hydraulic components with female NPTF ports (such as certain types of valves, manifolds, or equipment outlets) to hydraulic hoses or tubes that are terminated with female JIC swivel ends, particularly where a 90-degree change in line direction is required.
- Integrating equipment with female NPTF ports into hydraulic systems that predominantly utilize JIC flare connections, or vice-versa, while facilitating a necessary right-angle connection.
- Installations where the JIC swivel feature is crucial for simplifying alignment and preventing kinking or torsional stress on the hose assembly during installation.
- Commonly found in mobile equipment (e.g., construction machinery, agricultural vehicles), industrial machinery, manufacturing plants, and various general fluid power systems requiring versatile and reliable angled connections between differing thread standards.
Installation & Usage Guidelines
- Ensure all threads (female NPTF) and sealing surfaces (JIC 37° cone seat in the female swivel) are meticulously clean, undamaged, and free from any contaminants or debris prior to assembly.
- Thread a mating male NPTF pipe fitting into the female NPTF end of the Part 6503 elbow. While NPTF is designed as a Dryseal thread, it is often advisable to apply a compatible thread sealant (such as PTFE tape or liquid sealant) to the male NPTF threads, especially for high-pressure applications or if mating with standard NPT male threads, to ensure an optimal, leak-proof seal. Tighten to the recommended torque or industry best practice for the NPTF connection.
- Align the elbow to the desired 90-degree orientation. Then, connect the female JIC swivel end of the elbow to a mating male JIC fitting or a correctly flared tube end. The swivel nut allows the elbow body to be held stationary in the correct orientation while the nut is tightened independently to the recommended torque for the specific JIC size.
- Always use appropriate backup wrenches on the elbow body and the mating components during the tightening process to prevent distortion or damage to the fittings or the connected hydraulic lines.
- It's good practice to apply a light film of system-compatible lubricant to the threads of the JIC swivel nut (not on the sealing surfaces) to ensure smooth tightening and to help achieve the correct torque application.
