Part Number: FS2603

SAE ORFS Male Tee

Product Overview

The Delphi Fittings Part FS2603 is an SAE O-Ring Face Seal (ORFS) Male Tee. This fitting is designed to create a T-junction in a hydraulic line, allowing for the connection of three female ORFS swivel fittings or specially prepared tube ends. It features male ORFS flat face ends, each with an O-ring groove, on all three ports of the tee. The ORFS connection system is highly regarded for its exceptional leak-free performance, particularly in high-pressure hydraulic systems and applications experiencing significant vibration or pressure impulses. Manufactured from high-quality carbon steel and zinc-plated for robust corrosion resistance, the FS2603 tee adheres to SAE J1453 / ISO 8434-3 standards, ensuring consistent quality and interchangeability.

Key Features & Specifications

Material	High-Grade Carbon Steel
End 1 Configuration (Run)	Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3)
End 2 Configuration (Run)	Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3)
End 3 Configuration (Branch)	Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3)
Body Style	Tee, typically forged for strength, with flats or hexagonal features for wrench engagement.
Sealing Mechanism	All three 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 T-junction connecting three female ORFS swivel fittings or specially prepared tube ends of the same size, ensuring a high-integrity, leak-proof connection.
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 #FS2603 Series)

Delphi Fittings offers the FS2603 SAE ORFS Male Tee in a comprehensive range of common ORFS sizes. All three male ORFS ends are typically of the same size.

Examples include (Male ORFS x Male ORFS x Male ORFS):

FS2603-04: All ends 1/4" (-04) ORFS (9/16-18 UNF Thread)
FS2603-06: All ends 3/8" (-06) ORFS (11/16-16 UNF Thread)
FS2603-08: All ends 1/2" (-08) ORFS (13/16-16 UNF Thread)
FS2603-10: All ends 5/8" (-10) ORFS (1-14 UNS Thread)
FS2603-12: All ends 3/4" (-12) ORFS (1-3/16-12 UN Thread)
FS2603-16: All ends 1" (-16) ORFS (1-7/16-12 UN Thread)

Note: Each ORFS male end includes an appropriate O-ring. Reducing or unequal tees may be available under different part numbers or as special orders. For unlisted sizes, specific material requirements (e.g., stainless steel options), or other custom needs, please contact our sales team.

Applications

The Part FS2603 SAE ORFS Male Tee is essential for:

Creating a branch or splitting flow within a hydraulic circuit that utilizes ORFS connections throughout.
Connecting three hydraulic hoses or tubes that are terminated with female ORFS swivel fittings.
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 critical.
Applications requiring "zero clearance" assembly or disassembly, allowing for easier maintenance and component replacement in complex systems.
Providing multiple connection points in a compact, high-integrity fitting.

Installation & Usage Guidelines

Thoroughly inspect the O-ring grooves and flat sealing faces on all three male ends of the FS2603 tee, 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 or debris.
Verify that the O-rings supplied with (or intended for) the FS2603 tee 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 tee. Ensure the O-rings are properly seated and not twisted.
Align the tee with the three female ORFS swivel fittings or prepared tube ends that are to be connected.
Hand-tighten all three female ORFS swivel nuts onto the respective male ends of the tee until the flat faces make contact with the O-rings.
Use appropriately sized wrenches. While holding the central body of the FS2603 tee 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 crucial for correct O-ring compression and a reliable seal on all three ports.
After assembly and system pressurization, carefully inspect all three connections for any signs of leakage.

Why Choose Delphi Fittings Part FS2603?

Superior Leak Prevention: The O-Ring Face Seal design on all three ports provides exceptionally reliable, virtually leak-free connections, ideal for high-pressure and high-vibration hydraulic applications.
Versatile Branching: Allows for the creation of a robust T-junction entirely within the ORFS system, maintaining consistent sealing technology.
Zero Clearance Assembly Advantage: 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 (in this case, integral to the tee), allowing for multiple disconnections and reconnections with high reliability.
Durable Carbon Steel Construction: Manufactured from high-grade carbon steel for excellent strength and longevity in typical industrial and mobile hydraulic environments.
Enhanced Corrosion Resistance: Standard zinc plating provides robust protection against rust and other environmental corrosive factors.
Full Adherence to Industry Standards: Meets SAE J1453 / ISO 8434-3 specifications, ensuring compatibility and interchangeability with other standard ORFS components.
Quality-Assured Manufacturing: Produced under Delphi Fittings' rigorous ISO 9001:2015 certified quality management system.
