DELPHI FITTINGS
Part Number: 2503
37° JIC Male to NPTF Male Pipe 45° Elbow
Product Overview
The Delphi Fittings Part 2503 is a 45° adapter elbow engineered to create a secure, angular connection between a JIC (Joint Industry Council) 37° flare system and an NPTF (National Pipe Taper Fuel / Dryseal) threaded port. This fitting features a male JIC 37° flare on one end and a male NPTF pipe thread on the other, forming a 45-degree angle. It is commonly used to connect a hydraulic hose with a female JIC swivel nut or a flared tube to a component with a female NPTF port, where a gradual 45-degree change in direction is required for optimal routing. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 2503 elbow provides a reliable, leak-resistant transition between these two prevalent hydraulic connection types.

Note: Always verify the specific JIC and NPTF sizes required for your application. For unlisted size combinations, please contact our sales team.
Applications
The Part 2503 adapter elbow is ideal for interfacing JIC and NPTF systems where a 45-degree turn is needed:
- Connecting JIC hydraulic hoses or flared tubes to NPTF ports on hydraulic components where a gradual 45-degree change in direction is preferred for routing.
- Integrating equipment using JIC standards into systems predominantly featuring NPTF threads with an angular adjustment.
- Common in mobile equipment, agricultural machinery, industrial hydraulics, and general fluid power applications.
- Facilitating smoother flow paths compared to 90-degree elbows in certain layouts.
Installation & Usage Guidelines
- Ensure all threads and sealing surfaces are clean, undamaged, and free of contaminants.
- For the NPTF end, thread the male NPTF into the female NPTF port. Application of a compatible thread sealant to the male NPTF threads is recommended, especially if mating with a standard NPT port or for high-pressure scenarios. Tighten to achieve the desired 45-degree orientation and proper seal.
- Connect the male JIC end to the female JIC swivel nut. Ensure the 37° flare surfaces align correctly. Tighten the JIC nut to the recommended torque. No sealant is used on the JIC flare connection.
- Use backup wrenches on the elbow body and mating components as needed to prevent distortion or damage during tightening.
