DELPHI FITTINGS
Product Overview
The Delphi Fittings Part FS6402 is a straight adapter designed to connect a male SAE O-Ring Face Seal (ORFS) port or fitting to a male JIC (37° flare) fitting or flared tube end. This adapter features a male ORFS end with its distinctive flat face and O-ring groove on one side, and a female JIC 37° swivel nut on the other. The ORFS connection offers superior leak protection, especially in high-pressure and high-vibration applications, while the JIC swivel end allows for easy installation and alignment without twisting the mating JIC component or hose. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the FS6402 adapter is ideal for reliably transitioning between these two popular hydraulic sealing technologies, conforming to SAE J1453 (ORFS) and SAE J514 (JIC) standards.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3) |
| End 2 Configuration | Female 37° JIC Swivel Nut (conforming to SAE J514 / ISO 8434-2) |
| Body Style | Straight Adapter with hexagonal (hex) features for secure wrench engagement. |
| Sealing Mechanism | ORFS End: Utilizes an elastomeric O-ring (seated in the groove on the male ORFS face) which compresses against the flat face of the mating female ORFS swivel fitting, creating a high-integrity static face seal. 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. |
| Primary Function | To provide a straight, leak-proof connection from a male SAE ORFS fitting or port to a male JIC fitting or flared tube end, with the convenience of a JIC swivel nut. |
| O-Ring Material (for ORFS end) | Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request for specific fluid or temperature compatibility. O-ring is supplied with the ORFS end. |
| Plating & Finish | Cr3+ Trivalent Zinc Clear (ASTM B117 salt spray tested) |
| Reference Standard | SAE J1453 / ISO 8434-3 (O-Ring Face Seal Standard) |

Specific Applications & Hydraulic Circuit Routing
Part FS6402 fittings provide reliable fluid power conveyance in demanding mobile and stationary equipment circuits:
- High-Vibration Mobile Equipment: Excavator booms, mining equipment, and hydrostatic drives where Part FS6402 prevents hydraulic weeping under intense shock loads.
- Zero-Clearance Manifold Assembly: Flat face design allows slip-in component replacement without springing or spreading rigid hydraulic tubes.
- Extreme Pressure Impulse Circuits: Elastomeric face seal remains 100% leak-free throughout repetitive thermal cycles and impulse spikes.
Installation & Assembly Guidance
- O-Ring Retention Inspection: Inspect the machined face groove to ensure the O-ring is properly seated and retained prior to mating.
- Face-to-Face Alignment: Bring the flat faces into parallel contact before hand-threading the swivel nut to avoid pinching the O-ring.
- Calibrated Torque Tightening: Tighten the nut to the specified SAE J1453 torque value using a calibrated torque wrench.
- Dual-Wrench Counter-Torque: Always hold the fitting body hex with a backup wrench while torquing the connection to prevent twisting.
