DELPHI FITTINGS
Part Number: FS2650
SAE ORFS Male Cross
Product Overview
The Delphi Fittings Part FS2650 is an SAE O-Ring Face Seal (ORFS) Male Cross. This fitting is designed to create a four-way intersection in a hydraulic line, allowing for the connection of four female ORFS swivel fittings or specially prepared tube ends at 90-degree angles to each other. It features male ORFS flat face ends, each with an O-ring groove, on all four ports of the cross. The ORFS connection system ensures superior leak-free performance, making it ideal for high-pressure hydraulic systems and applications subject to vibration and pressure surges. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the FS2650 cross conforms to SAE J1453 / ISO 8434-3 standards, guaranteeing reliability and interchangeability.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| Port 1 Configuration | Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3) |
| Port 2 Configuration | Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3) |
| Port 3 Configuration | Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3) |
| Port 4 Configuration | Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3) |
| Body Style | Cross, typically forged for strength, with flats or hexagonal features for wrench engagement. |
| Sealing Mechanism | All four ends utilize an elastomeric O-ring (seated in the groove on each male ORFS face) which compresses against the flat face of the mating female ORFS swivel fitting or prepared tube end, creating a superior static face seal. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability and resistance to environmental corrosion. |
| Primary Function | To provide a four-way junction connecting four female ORFS swivel fittings or specially prepared tube ends of the same size at 90-degree angles, ensuring high-integrity, leak-proof connections. |
| Working Pressure | Suitable for high-pressure hydraulic systems, often rated up to 6000 PSI or higher depending on size and specific application. |
| O-Ring Material (for all ORFS 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 the fitting. |
Commonly Available Sizes (Part #FS2650 Series)

- FS2650-08: All ends 1/2" (-08) ORFS (13/16-16 UNF Thread)
- FS2650-10: All ends 5/8" (-10) ORFS (1-14 UNS Thread)
- FS2650-12: All ends 3/4" (-12) ORFS (1-3/16-12 UN Thread)
Note: Each ORFS male end includes an appropriate O-ring. For unlisted sizes, specific material requirements (e.g., stainless steel options), or other custom needs, please contact our sales team.
Applications
The Part FS2650 SAE ORFS Male Cross is valuable for:
- Creating a central distribution or collection point in a hydraulic circuit, allowing flow to be split into three directions or combined from three directions into one.
- Connecting four hydraulic hoses or tubes that are terminated with female ORFS swivel fittings in a compact cross configuration.
- Use in demanding hydraulic systems on mobile equipment (such as construction, agriculture, and forestry machinery), industrial machinery, and manufacturing systems where the superior leak protection of ORFS fittings is essential.
- Applications requiring "zero clearance" assembly or disassembly for easier maintenance of connected lines.
- Providing multiple connection points from a single fitting body, potentially reducing the total number of fittings in a complex system.
Installation & Usage Guidelines
- Thoroughly inspect the O-ring grooves and flat sealing faces on all four male ends of the FS2650 cross, as well as the flat faces and O-rings of the mating female ORFS swivel fittings or prepared tube ends. Ensure all surfaces are meticulously clean, undamaged, and free from any contaminants.
- Verify that the O-rings supplied with (or intended for) the FS2650 cross are of the correct size and material (e.g., Buna-N, Viton®) for the application's fluid, temperature, and pressure.
- Correctly install a lubricated O-ring into the groove on each male ORFS face of the cross. Ensure the O-rings are properly seated and not twisted.
- Align the cross with the four female ORFS swivel fittings or prepared tube ends that are to be connected.
- Hand-tighten all four female ORFS swivel nuts onto the respective male ends of the cross until the flat faces make contact with the O-rings.
- Use appropriately sized wrenches. While holding the central body of the FS2650 cross stationary with a backup wrench (if design allows and practical), tighten each female ORFS swivel nut to the manufacturer's recommended torque value or by using the "Flats From Wrench Resistance" (FFWR) method if specified for the respective ORFS size. Proper torque is critical for correct O-ring compression and a reliable seal on all four ports.
- After assembly and system pressurization, carefully inspect all four connections for any signs of leakage.
Why Choose Delphi Fittings Part FS2650?
- Superior Leak Prevention: The O-Ring Face Seal design on all four ports provides an exceptionally reliable, virtually leak-free connection, ideal for high-pressure and high-vibration hydraulic applications.
- Versatile Four-Way Connection: Allows for the creation of complex junctions, splitting or combining fluid paths efficiently.
- Zero Clearance Assembly Benefit: Facilitates easier installation and removal of connected lines or components without needing significant displacement of adjacent parts.
- High-Pressure Capability: Engineered to withstand the demanding pressures commonly encountered in modern hydraulic systems.
- Excellent Reusability: The ORFS connection relies on replaceable O-rings on the male fittings (integral to this cross), allowing for multiple disconnections and reconnections with high reliability.
- Durable Carbon Steel Construction: Manufactured from high-grade carbon steel for excellent strength and longevity.
- Enhanced Corrosion Resistance: Standard zinc plating provides robust protection against rust and environmental factors.
- Full Adherence to Industry Standards: Meets SAE J1453 / ISO 8434-3 specifications, ensuring compatibility and interchangeability with other standard ORFS components.
