DELPHI FITTINGS
Part Number: 6505
NPTF Male Pipe x 37° JIC Female Swivel Nut Adapter
Product Overview
The Delphi Fittings Part 6505 is a straight adapter designed to connect a male NPTF (National Pipe Taper Fuel / Dryseal) pipe or fitting to a JIC (Joint Industry Council) 37° flare connection, specifically a female JIC swivel nut typically found on hose assemblies. This adapter features a male NPTF pipe thread on one end and a female JIC 37° swivel nut on the other, providing a direct, in-line transition between these two widely used hydraulic thread standards. The JIC swivel end allows for easy alignment and installation without imparting twist to 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 6505 ensures a secure and leak-resistant connection for various hydraulic applications.
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) |
| Body Style | Straight Adapter/Connector 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 in a straight line, effectively adapting between these two common thread types while allowing for easy installation due to the swivel feature. |
| Working Pressure | Suitable for high-pressure hydraulic applications. Specific pressure ratings vary depending on the size of the fitting. |

Applications
The Part 6505 NPTF Male Pipe x JIC Female Swivel Nut Adapter is ideal for:
- Directly connecting components with male NPTF threads (such as pumps, valves, cylinders, or manifolds) to hydraulic hoses or tubes that are terminated with female JIC swivel ends.
- Integrating NPTF standard components into hydraulic systems that primarily utilize JIC flare connections, or vice-versa, for in-line connections.
- Situations where the swivel feature of the JIC end is beneficial for simplifying installation, preventing hose twist, and ensuring correct alignment without stressing the assembly.
- Common usage in a wide array of hydraulic systems across industries like mobile equipment (construction, agriculture), industrial machinery, manufacturing equipment, and general fluid power applications.
Installation & Usage Guidelines
- Thoroughly inspect all threads (male NPTF) and sealing surfaces (JIC 37° cone seat in the female swivel) to ensure they are clean, undamaged, and free from any contaminants or debris before commencing assembly.
- For the male NPTF end of the adapter: Apply a compatible pipe thread sealant (such as PTFE tape or liquid sealant) to the male NPTF threads. This is especially recommended if mating with a standard NPT female port or for high-pressure applications to ensure an optimal, leak-proof seal. Thread the NPTF end into the mating female NPTF port and tighten to the recommended torque or industry best practice for the specific size and application.
- For the female JIC swivel end: Align the adapter with the mating male JIC fitting or flared tube end. The swivel nut allows the adapter body to be held stationary while the nut is tightened independently. Hand-tighten the swivel nut, then use a wrench to tighten to the recommended torque for the JIC size. It is good practice to apply a light coat of system-compatible lubricant to the threads of the swivel nut (avoiding the sealing cone) to ensure smooth tightening and accurate torque application.
- Always use appropriate backup wrenches on the adapter body and the mating components during the tightening process to prevent distortion, over-tightening, or damage to the fittings or connected lines.
