DELPHI FITTINGS
Part Number: 6506
NPTF Female Pipe x 37° JIC Female Swivel Nut Adapter
Product Overview
The Delphi Fittings Part 6506 is a straight adapter meticulously designed to connect a female NPTF (National Pipe Taper Fuel / Dryseal) port to a JIC (Joint Industry Council) 37° flare connection, specifically a female JIC swivel nut commonly found on hydraulic hose assemblies. This adapter features a female 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 distinct and widely used hydraulic thread standards. The integral JIC swivel end is crucial for facilitating easy alignment and installation, preventing any torsional stress or twisting of the connected hose. Manufactured from high-quality carbon steel and zinc-plated for superior corrosion resistance, the Part 6506 ensures a durable, secure, and leak-resistant connection suitable for various demanding hydraulic applications.
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) |
| Body Style | Straight Adapter/Connector with hexagonal features for secure wrench tightening. |
| Sealing Mechanism | NPTF End: Designed to seal with a mating male NPTF pipe fitting (Dryseal). If connecting to a standard NPT male fitting, the use of a compatible thread sealant is recommended for optimal sealing. JIC End: Achieves a metal-to-metal seal on the 37° cone seat located inside the female swivel end when connected to a mating male JIC 37° flare fitting or a correctly flared tube end. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability and resistance to environmental corrosion. |
| Primary Function | To connect a component with a female NPTF port (e.g., valve, manifold) to a hydraulic hose or tube assembly equipped with a female JIC swivel end, in a straight line, effectively adapting between these two thread types. |
| Working Pressure | Suitable for high-pressure hydraulic applications. Specific pressure ratings are dependent on the size of the fitting and should be verified for the intended use. |

Applications
The Part 6506 NPTF Female Pipe x JIC Female Swivel Nut Adapter is frequently used in:
- Connecting hydraulic components with female NPTF ports (such as certain types of valves, manifolds, equipment outlets, or filter housings) directly to hydraulic hoses or rigid tubes that are terminated with female JIC swivel ends.
- Integrating equipment or components with female NPTF ports into hydraulic systems that predominantly utilize JIC flare connections, or vice-versa, for straight, in-line connections.
- Installations where the swivel feature of the JIC end is particularly beneficial, simplifying the connection process by allowing the nut to be tightened without rotating the hose, thus preventing kinking or torsional stress.
- Common applications across diverse industries including mobile equipment (e.g., construction machinery, agricultural vehicles), industrial machinery, manufacturing plants, and various general fluid power systems requiring versatile and reliable straight connections between different thread standards.
Installation & Usage Guidelines
- Thoroughly inspect all threads (female NPTF end of the adapter and mating male NPTF fitting) and all JIC sealing surfaces (37° cone seat in the adapter's female swivel end and the mating male JIC flare) to ensure they are clean, undamaged, and free from any contaminants or debris.
- Thread a mating male NPTF pipe fitting into the female NPTF end of the Part 6506 adapter. While NPTF is designed as a Dryseal thread, for optimal sealing, especially in high-pressure scenarios or if mating with a standard NPT male fitting, the application of a compatible thread sealant (such as PTFE tape or liquid pipe sealant) to the male NPTF threads is often recommended. Tighten to the appropriate torque or industry best practice for the NPTF connection size.
- Align the adapter as needed. Then, connect the female JIC swivel end of the adapter to a mating male JIC fitting or a correctly flared tube end. The swivel nut feature allows the adapter body to be held stationary while the nut is tightened independently to the recommended torque for the specific JIC size.
- 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. A light application of system-compatible lubricant to the JIC swivel nut threads (avoiding the sealing cone) can aid in achieving proper torque and smooth assembly.
