DELPHI FITTINGS
Product Overview
The Delphi Fittings Part FS6412 is a straight adapter engineered to provide a high-integrity connection between a male SAE O-Ring Face Seal (ORFS) fitting or prepared tube end and a female SAE O-Ring Boss (ORB) port. This robust adapter features a female ORFS swivel nut with its distinctive flat sealing face on one end, and a male SAE ORB thread with an O-ring groove on the other. The O-Ring Face Seal connection is renowned for its exceptional leak protection in high-pressure and high-vibration hydraulic systems, and the ORFS swivel nut facilitates easy, stress-free installation. The SAE O-Ring Boss end also offers a superior seal. Manufactured from high-quality carbon steel and zinc-plated for excellent corrosion resistance, the FS6412 adapter is ideal for reliably transitioning between these two advanced sealing technologies in demanding applications, conforming to SAE J1453 (ORFS) and SAE J1926 (ORB) standards.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Female SAE O-Ring Face Seal (ORFS) Swivel Nut (conforming to SAE J1453 / ISO 8434-3) |
| End 2 Configuration | Male SAE O-Ring Boss (ORB) (conforming to SAE J1926-1 / ISO 11926-1) |
| Body Style | Straight Adapter with hexagonal (hex) features for secure wrench engagement. |
| Sealing Mechanism | ORFS Female Swivel End: Seals with the O-ring on a mating male ORFS fitting against its flat face. The swivel nut allows for easy alignment and tightening without twisting the connected hose or tube. ORB Male End: Utilizes an elastomeric O-ring (seated in the groove on the male ORB fitting) which seals against the chamfered boss of the mating female ORB port. |
| Primary Function | To provide a straight, leak-proof connection from a male ORFS fitting or prepared tube end to a female SAE ORB port, with the convenience of an ORFS swivel nut for ease of installation. |
| O-Ring Material (for ORB male end) | Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request for specific fluid or temperature compatibility. The O-ring is supplied with the ORB male end of this adapter. (The mating male ORFS fitting will have its own O-ring). |
| 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 FS6412 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 FS6412 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.
