DELPHI FITTINGS
Part Number: 6565
37° JIC Female Swivel x 37° JIC Female Swivel Nut Union
Product Overview
The Delphi Fittings Part 6565 is a 37° JIC Female Swivel x JIC Female Swivel Nut Union. This straight connector is expertly designed to join two male JIC 37° flare fittings or flared tube ends in a direct line. It uniquely features female JIC 37° swivel nuts on both ends, offering maximum flexibility during installation. This dual-swivel design allows for easy alignment and tightening of both connections independently, without imparting any torsional stress on the connected hoses or tubes. It is particularly advantageous for connecting two fixed male JIC ports or in applications where precise alignment and stress-free assembly are critical. Manufactured from high-quality carbon steel and zinc-plated for superior corrosion resistance, the Part 6565 union ensures a secure, high-integrity, leak-proof connection that conforms to SAE J514 standards.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Female 37° JIC Swivel Nut (per SAE J514 / ISO 8434-2) |
| End 2 Configuration | Female 37° JIC Swivel Nut (per SAE J514 / ISO 8434-2) |
| Body Style | Straight Union/Connector, typically with a central hexagonal section or flats for secure wrench engagement during tightening. |
| Sealing Mechanism | Both ends achieve a metal-to-metal seal on the 37° cone seat located inside each female swivel end when connected to respective mating male JIC 37° flare fittings or correctly flared tube ends. |
| Corrosion Protection | Standard Zinc Plating for robust protection against rust and environmental corrosion. |
| Primary Function | To connect two male JIC 37° flare fittings or flared tube ends in a straight line, providing the convenience of swivel nuts on both ends for simplified installation, optimal alignment, and prevention of hose/tube twist. |
| Working Pressure | Suitable for demanding high-pressure hydraulic applications. Specific pressure ratings are dependent on the size of the fitting. |

Applications
The Part 6565 JIC Female Swivel x JIC Female Swivel Union is frequently utilized for:
- Joining two male JIC ended hydraulic hoses, rigid tubes, or fixed fittings in a straight, in-line configuration.
- Applications where both connecting components are fixed or have limited maneuverability, and the dual swivel nuts provide the essential freedom for easy alignment and stress-free tightening.
- Ideal for repairing or extending existing hydraulic lines where male JIC connections are present on both sides of the union point.
- Commonly employed in various hydraulic systems across diverse industries such as mobile equipment (e.g., construction machinery, agricultural vehicles), industrial machinery, manufacturing plants, and material handling equipment where flexible yet secure JIC connections are paramount.
- Simplifying complex plumbing by allowing sections to be connected without precise pre-alignment of the male ends.
Installation & Usage Guidelines
- Thoroughly inspect all mating male JIC 37° flare sealing surfaces and the internal 37° cone seats of the Part 6565 union to ensure they are perfectly clean, undamaged, and free from any nicks, scratches, or contaminants.
- Align the union with the two male JIC fittings or flared tube ends that are to be connected.
- Hand-tighten both female JIC swivel nuts onto the respective male JIC ends until the sealing surfaces make contact.
- Use appropriately sized wrenches to tighten each swivel nut to the manufacturer's recommended torque specification for the particular JIC size. If a central hex is present on the union body, it can be held with a backup wrench to prevent rotation of the entire assembly while tightening the nuts.
- The dual swivel nuts allow each connection to be tightened independently and oriented correctly without transferring torsional stress to the connected hoses or tubes.
- No thread sealant is required for JIC flare connections, as the seal is achieved by the precise metal-to-metal contact of the 37° flare and cone surfaces. A light application of system-compatible lubricant on the threads of the swivel nuts (not on the sealing surfaces themselves) can facilitate smooth tightening and help achieve the correct torque.
