DELPHI FITTINGS
Part Number: FS2703
SAE ORFS Male Bulkhead Branch Tee
Product Overview
The Delphi Fittings Part FS2703 is an SAE O-Ring Face Seal (ORFS) Male Bulkhead Branch Tee. This specialized fitting is designed to create a T-junction for hydraulic lines where one of the branch connections needs to pass through a panel, bulkhead, or equipment wall, providing a secure mounting point. It typically features male ORFS flat face ends with O-ring grooves on all three ports (two on the run and one on the bulkhead branch) and includes a locknut for panel installation. This configuration is ideal for routing a hydraulic line to or from a panel while also splitting or joining with other ORFS lines. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the FS2703 bulkhead branch tee conforms to SAE J1453 / ISO 8434-3 standards, ensuring high-integrity, leak-free performance in demanding hydraulic systems.
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 (Bulkhead Branch) | Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3) |
| Body Style | Bulkhead Branch Tee with a threaded body section on one branch for panel mounting and a separate locknut. Hexagonal features for wrenching. |
| Sealing Mechanism | All ORFS 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. Bulkhead Seal: The locknut mechanically secures the branch of the tee to the panel. An additional washer or sealant may be used by the installer for environmental sealing if required. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability and resistance to environmental corrosion. |
| Included Component | Locknut (e.g., Part FS306 ORFS Bulkhead Locknut) for the bulkhead branch end. |
| Primary Function | To provide a T-junction for ORFS hydraulic lines where one branch passes through and is secured to a panel or bulkhead, connecting to female ORFS swivel fittings or prepared tubes on all three ports. |
| Working Pressure | Suitable for high-pressure hydraulic systems, often rated up to 6000 PSI or higher depending on size. |
| O-Ring Material (for all ORFS ends) | Typically Buna-N (Nitrile) 90 Durometer as standard. Viton® (FKM) or other materials available upon request. O-rings are supplied with the fitting. |
Commonly Available Sizes (Part #FS2703 Series)
Delphi Fittings offers the FS2703 SAE ORFS Male Bulkhead Branch Tee in a range of common ORFS sizes. All three male ORFS ends are typically of the same size.
Examples include (Male ORFS Run x Male ORFS Run x Male ORFS Bulkhead Branch):
- FS2703-04: All ends 1/4" (-04) ORFS (9/16-18 UNF Thread)
- FS2703-06: All ends 3/8" (-06) ORFS (11/16-16 UNF Thread)
- FS2703-08: All ends 1/2" (-08) ORFS (13/16-16 UNF Thread)
- FS2703-10: All ends 5/8" (-10) ORFS (1-14 UNS Thread)
- FS2703-12: All ends 3/4" (-12) ORFS (1-3/16-12 UN Thread)
Note: Each bulkhead branch tee includes a corresponding locknut (e.g., Part FS306) and O-rings for all ORFS male ends. For unlisted sizes, specific material requirements (e.g., stainless steel options), or other custom needs, please contact our sales team.
Applications
The Part FS2703 SAE ORFS Male Bulkhead Branch Tee is essential for:
- Creating a T-junction in a hydraulic circuit where one of the lines needs to pass through an equipment wall, chassis, or control panel, allowing for a secure external or internal take-off point.
- Providing a fixed and robust branching point on a panel for hydraulic hoses or tubes terminated with female ORFS swivel fittings.
- Use in mobile equipment, industrial machinery, agricultural vehicles, and any system requiring a panel-mounted tee connection for high-integrity ORFS lines, especially where space optimization and neat routing are important.
- Situations where a fluid line needs to be split or merged at a bulkhead interface, maintaining the superior sealing performance of ORFS connections throughout.
Installation & Usage Guidelines
- Prepare the panel or bulkhead by drilling or punching an appropriately sized hole for the threaded body of the bulkhead branch on the FS2703 tee.
- Ensure the panel surface around the hole is clean and flat.
- Insert the threaded body of the bulkhead branch through the prepared hole from the desired side.
- Slide the provided locknut over the protruding threads on the opposite side of the panel and tighten it securely against the panel surface. Use a wrench on the tee's body flats to prevent it from rotating during tightening.
- Verify that the O-rings for all three ORFS male ends are correctly sized, lubricated, and properly seated in their grooves without damage.
- Connect the male ORFS ends of the tee to the mating female ORFS swivel fittings or prepared tube ends. Hand-tighten the swivel nuts until the flat faces meet the O-rings.
- Using appropriate wrenches (one to hold the tee body if necessary, and one for each swivel nut), tighten each ORFS connection to the manufacturer's recommended torque or by using the "Flats From Wrench Resistance" (FFWR) method.
