DELPHI FITTINGS
Part Number: FS6803
SAE ORFS Male x SAE ORB Male Branch Tee
Product Overview
The Delphi Fittings Part FS6803 is a specialized branch tee adapter designed to integrate different high-performance hydraulic connection standards. This fitting typically features two male SAE O-Ring Boss (ORB) threaded ends on the straight-through 'run' portion and a male SAE O-Ring Face Seal (ORFS) connection with its distinctive flat face and O-ring groove on the 90-degree branch. This configuration is ideal for applications where a main hydraulic line utilizes ORB connections and requires a branch take-off for a component or line that uses the ORFS sealing system, known for its excellent performance in high-vibration environments. Manufactured from high-quality carbon steel and zinc-plated for robust corrosion resistance, the FS6803 tee provides a reliable and leak-free solution for complex hydraulic plumbing, conforming to SAE J1453 (ORFS) and SAE J1926 (ORB) standards.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| Run End 1 Configuration | Male SAE O-Ring Boss (ORB) (conforming to SAE J1926-1 / ISO 11926-1) |
| Run End 2 Configuration | Male SAE O-Ring Boss (ORB) (conforming to SAE J1926-1 / ISO 11926-1) |
| Branch End Configuration | Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3) |
| Body Style | Branch Tee Adapter, typically forged for strength, with hexagonal (hex) features or flats for secure wrench engagement. |
| Sealing Mechanism | ORB Ends (Run): Both utilize an elastomeric O-ring (seated in grooves on the male ORB fittings) which seals against the chamfered boss of the mating female ORB ports, providing highly reliable, leak-proof seals. ORFS End (Branch): 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 superior static face seal. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability and resistance to environmental corrosion. |
| Primary Function | To create a 90-degree branch with a male ORFS connection from a main line that has female ORB ports on both run ends, allowing for the integration of an ORFS line or component into an ORB system. |
| Working Pressure | Suitable for high-pressure hydraulic systems. Specific pressure ratings depend on the size of the fitting and the operational conditions. |
| 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. |

Applications
The Part FS6803 SAE ORFS Male x SAE ORB Male Branch Tee is ideal for:
- Creating an ORFS branch line from a main hydraulic line that utilizes SAE ORB connections. This is highly useful for adding components that require the exceptional sealing of ORFS, such as in high-vibration zones or critical connections.
- Integrating test points, pressure gauges (with a female ORFS connection), sensors, or auxiliary hydraulic circuits into an existing ORB-based system.
- Use in demanding hydraulic applications on mobile equipment, industrial machinery, and manufacturing systems where a reliable T-junction with mixed high-performance sealing types is required.
- Systems where the robust O-Ring Boss seal is preferred for the main run connections, and the O-Ring Face Seal offers superior performance for the branch connection, particularly for ease of assembly ("zero clearance") or vibration resistance.
Installation & Usage Guidelines
- Ensure all ORB male threads, O-ring grooves on ORB ends, the ORFS male flat face and O-ring groove on the branch, and all mating port/fitting surfaces are meticulously clean, undamaged, and free from any contaminants.
- Verify that the O-rings for all male ends (two ORB, one ORFS) are the correct size and material (e.g., Buna-N, Viton®) for the application. Ensure all O-rings are correctly lubricated with a system-compatible fluid.
- Carefully install the lubricated O-rings into the grooves on all three male ends of the tee.
- Thread the male ORB run ends of the tee into the respective female ORB ports by hand until the O-rings make initial contact and the fitting shoulders seat. Before fully tightening, orient the tee so the ORFS branch faces the desired direction.
- Once oriented, use a wrench on the tee's hex body or flats to tighten both ORB run connections to the manufacturer's recommended torque specification for the ORB size.
- Align the male ORFS branch end of the adapter with the mating female ORFS swivel fitting or prepared tube end. Hand-tighten the ORFS swivel nut until the flat faces make contact and the O-ring is engaged.
- Use appropriate wrenches to tighten the ORFS branch connection. While holding the tee body stationary, tighten the female ORFS swivel nut to the manufacturer's recommended torque value or by using the "Flats From Wrench Resistance" (FFWR) method if specified.
- Always use backup wrenches on the tee body and mating components during tightening to prevent distortion or damage. For stainless steel versions (if applicable), using a thread lubricant or anti-seize compound is crucial.
