DELPHI FITTINGS
Product Overview
The Delphi Fittings Part 6504 is a straight 37° JIC Male to JIC Female Swivel Connector. This adapter is designed to provide a straight, in-line connection between two JIC components, featuring a male JIC 37° flare on one end and a female JIC 37° swivel nut on the other. The swivel feature on the female end is crucial for easy installation and alignment, especially when connecting to hydraulic hoses or tubes, as it prevents twisting and ensures a stress-free connection. Manufactured from high-quality carbon steel and zinc-plated for enhanced corrosion resistance, the Part 6504 connector guarantees a reliable, leak-proof seal in hydraulic systems compliant with SAE J514 standards.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Male 37° JIC Flare (per SAE J514 / ISO 8434-2) |
| End 2 Configuration | Female 37° JIC Swivel Nut (per SAE J514 / ISO 8434-2) |
| Body Style | Straight Connector/Adapter with hexagonal features for secure wrench tightening. |
| Sealing Mechanism | Both ends utilize a metal-to-metal seal: the male end on its 37° flare cone, and the female swivel end on its internal 37° cone seat, when connected to respective mating JIC fittings. |
| Primary Function | To connect a male JIC flare fitting to another male JIC flare fitting or a flared tube in a straight line, with the female swivel end facilitating easy orientation and preventing torsional stress on the connected line during tightening. |
| Plating & Finish | Cr3+ Trivalent Zinc Clear (ASTM B117 salt spray tested) |
| Applicable Standard | SAE J514 / ISO 8434-2 (ANSI B1.20.3 for NPTF threads) |

Specific Applications & Hydraulic Circuit Routing
Part 6504 fittings provide reliable, high-integrity connections across demanding mobile and stationary fluid power applications:
- Industrial Hydraulic Machinery: High-pressure hydraulic circuits, power packs, and hydraulic manifolds utilizing Part 6504 for reliable fluid conveyance.
- Mobile & Construction Equipment: Excavators, agricultural machinery, and heavy equipment subject to vibration, pressure pulsations, and harsh operating conditions.
- Fluid Routing & Manifold Transition: Facilitates smooth tube-to-hose or port-to-tube connections without imposing residual mechanical stress on hydraulic lines.
Installation & Assembly Guidance
- Surface & Thread Inspection: Ensure all male 37° flare surfaces, mating female cones, and thread flanks are clean, smooth, and free of burrs or contaminants.
- Finger-Tight Alignment: Align the mating connections coaxially and thread the connection by hand until fully seated finger-tight.
- Flats From Finger Tight (F.F.F.T.): Tighten the nut or hex body using the recommended SAE flats-from-finger-tight (FFFT) method or calibrated torque wrench to achieve proper metal-to-metal cone engagement.
- Dual-Wrench Backup Practice: Always support the fitting body hex with a backup wrench while tightening the mating nut or pipe connection to prevent inadvertent loosening.
