DELPHI FITTINGS
Part Number: FS2500
SAE ORFS Male 90° Elbow
Product Overview
The Delphi Fittings Part FS2500 is an SAE O-Ring Face Seal (ORFS) Male 90° Elbow. This fitting is designed to create a 90-degree change in direction within a hydraulic line, connecting two female ORFS swivel fittings or specially prepared tube ends. It features male ORFS flat face ends, each with an O-ring groove, on both ports of the elbow. The ORFS connection is renowned for its superior leak-free performance, especially in high-pressure systems and applications subject to vibration and impulse. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the FS2500 elbow conforms to SAE J1453 / ISO 8434-3 standards, ensuring reliability and interchangeability.
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 | Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3) |
| Angle | 90 Degrees |
| Body Style | Elbow, typically forged for strength, with hexagonal (hex) features or flats for secure wrench engagement. |
| Sealing Mechanism | Both 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 highly effective static face seal. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability and resistance to environmental corrosion. |
| Primary Function | To provide a 90-degree, high-integrity, and leak-proof connection between two female ORFS swivel fittings or specially prepared tube ends of the same size. |
| Working Pressure | Suitable for high-pressure hydraulic systems, often rated up to 6000 PSI or higher depending on size and application. |
| O-Ring Material (for both 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. |

Applications
The Part FS2500 SAE ORFS Male 90° Elbow is essential for:
- Creating a 90-degree change in direction when connecting two hydraulic hoses or tubes that are terminated with female ORFS swivel fittings.
- Optimizing hydraulic line routing in tight spaces or around obstructions in systems where ORFS fittings are specified for their superior sealing.
- Use in demanding hydraulic applications found in mobile equipment (such as construction, agriculture, and mining machinery), industrial machinery, and manufacturing systems that experience high pressures, vibrations, or thermal cycling.
- Applications requiring "zero clearance" assembly or disassembly, as the ORFS design allows for easier installation and removal of components.
Installation & Usage Guidelines
- Thoroughly inspect the O-ring grooves and flat sealing faces on both male ends of the FS2500 elbow, 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 FS2500 elbow are of the correct size and material (e.g., Buna-N, Viton®) for the specific application's fluid, temperature, and pressure.
- Correctly install a lubricated O-ring into the groove on each male ORFS face of the elbow. Ensure the O-rings are properly seated and not twisted.
- Align the elbow with the two female ORFS swivel fittings or prepared tube ends that are to be connected.
- Hand-tighten both female ORFS swivel nuts onto the respective male ends of the elbow until the flat faces make contact with the O-rings.
- Use appropriately sized wrenches. While holding the central hex or flats of the FS2500 elbow body stationary with a backup wrench, 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.
- After assembly and system pressurization, carefully inspect both connections for any signs of leakage.
Why Choose Delphi Fittings Part FS2500?
- Superior Leak Prevention: The O-Ring Face Seal design provides an exceptionally reliable, virtually leak-free 90-degree connection, crucial for high-pressure and high-vibration hydraulic applications.
- Optimized Flow Path: The 90-degree elbow allows for efficient changes in fluid direction within a hydraulic circuit.
- Zero Clearance Assembly: Facilitates easier installation and removal of components in tight spaces without requiring significant displacement of adjacent lines.
- High-Pressure Capability: Engineered to withstand the demanding pressures commonly encountered in modern hydraulic systems.
- Excellent Reusability: The ORFS connection relies on a replaceable O-ring on the male fitting (in this case, part of the elbow), 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 corrosive factors.
- Full Adherence to Industry Standards: Meets SAE J1453 / ISO 8434-3 specifications, ensuring compatibility and interchangeability.
