DELPHI FITTINGS
Product Overview
The Delphi Fittings Part FS6804 is a run tee adapter, expertly designed to integrate different high-performance hydraulic connection standards within a single, robust fitting. This tee typically features two male SAE O-Ring Face Seal (ORFS) ends on the straight-through 'run' portion, and one male SAE O-Ring Boss (ORB) threaded end on the 90-degree branch. This configuration allows a primary fluid line utilizing ORFS connections (known for superior sealing in high vibration) to have an ORB branch take-off, suitable for connecting to components with female ORB ports like valves, sensors, or manifolds. Manufactured from high-quality carbon steel and zinc-plated for excellent corrosion resistance, the FS6804 tee provides a reliable and leak-free solution for complex hydraulic plumbing, conforming to both SAE J1453 (ORFS) and SAE J1926 (ORB) standards.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| Run End 1 Configuration | Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3) |
| Run End 2 Configuration | Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3) |
| Branch End Configuration | Male SAE O-Ring Boss (ORB) (conforming to SAE J1926-1 / ISO 11926-1) |
| Body Style | Run Tee Adapter, typically forged for strength, with hexagonal (hex) features or flats for secure wrench engagement. |
| Sealing Mechanism | ORFS Ends (Run): Utilize elastomeric O-rings (seated in grooves on the male ORFS faces) which compress against the flat faces of mating female ORFS swivel fittings, creating a high-integrity static face seal. ORB End (Branch): 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 create a T-junction providing a male ORB branch connection from a main line that uses male ORFS connections on both run ends, thereby connecting to three female-ported components. |
| O-Ring Material (for all male ends) | Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request for specific fluid or temperature compatibility. O-rings are supplied with all male ends. |
| 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 FS6804 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 FS6804 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.
