Part Number: FS2704

SAE ORFS Male Bulkhead Run Tee

Product Overview

The Delphi Fittings Part FS2704 is an SAE O-Ring Face Seal (ORFS) Male Bulkhead Run Tee. This specialized tee fitting is designed to allow the straight-through ('run') portion of the connection to pass through a panel or bulkhead, while also providing a 90-degree branch. All three ports feature male ORFS flat face ends with O-ring grooves, ensuring high-integrity, leak-free seals. A locknut is included to securely fasten the 'run' section to the panel. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the FS2704 bulkhead run tee conforms to SAE J1453 / ISO 8434-3 standards, making it ideal for applications requiring a robust, panel-mounted T-junction with superior ORFS sealing performance.

Key Features & Specifications

Material	High-Grade Carbon Steel
Run End 1 (Bulkhead)	Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3)
Run End 2	Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3)
Branch End	Male SAE O-Ring Face Seal (ORFS) (conforming to SAE J1453 / ISO 8434-3)
Body Style	Bulkhead Run Tee, where one end of the straight 'run' is extended and threaded for bulkhead mounting, with a separate locknut. The branch is at 90° to the run. 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. Bulkhead Seal: The locknut mechanically secures the run of the tee to the panel. An additional washer or sealant might be used for environmental sealing if required.
Corrosion Protection	Standard Zinc Plating for enhanced durability.
Included Component	Locknut (e.g., Part FS306 ORFS Bulkhead Locknut) for the bulkhead run end.
Primary Function	To provide a T-junction for ORFS hydraulic lines where the main straight-through 'run' passes through and is secured to a panel, with a 90-degree ORFS branch connection.
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 #FS2704 Series)

Delphi Fittings offers the FS2704 SAE ORFS Male Bulkhead Run Tee in a range of common ORFS sizes. All three male ORFS ends are typically of the same size.

Examples include (All ends Male ORFS):

FS2704-04: All ends 1/4" (-04) ORFS (9/16-18 UNF Thread)
FS2704-06: All ends 3/8" (-06) ORFS (11/16-16 UNF Thread)
FS2704-08: All ends 1/2" (-08) ORFS (13/16-16 UNF Thread)
FS2704-10: All ends 5/8" (-10) ORFS (1-14 UNS Thread)
FS2704-12: All ends 3/4" (-12) ORFS (1-3/16-12 UN Thread)

Note: Each bulkhead run 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 FS2704 SAE ORFS Male Bulkhead Run Tee is essential for:

Routing a main hydraulic line directly through an equipment wall, panel, or chassis while simultaneously providing a 90-degree ORFS branch connection on one side of the panel.
Creating a T-junction where the primary flow passes through a barrier, and a secondary ORFS line branches off from the run, ensuring high-integrity sealing at all points.
Commonly used in mobile equipment, control systems, agricultural machinery, and industrial equipment where efficient space utilization, secure panel mounting, and a reliable T-branch from a bulkhead line are required with ORFS connections.
Facilitating organized line management and providing a fixed point for both the run-through and branch connections at the panel interface, ideal for systems demanding "zero clearance" assembly.

Installation & Usage Guidelines

Prepare the panel or bulkhead by drilling or punching an appropriately sized hole for the extended threaded run section of the tee.
Ensure the panel surface around the hole is clean and flat.
Insert the extended threaded body of the run section through the prepared hole. The branch of the tee will typically be positioned on one side of the panel.
Secure the fitting using the provided locknut on the opposite side of the panel, tightening it firmly against the panel surface. Use a wrench on the fitting's hex or flats to prevent rotation 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 (both run ends and the branch end) 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, tighten each ORFS connection to the manufacturer's recommended torque or by using the "Flats From Wrench Resistance" (FFWR) method.

Why Choose Delphi Fittings Part FS2704?

Efficient Line Routing & Branching Through Panel: Allows a main ORFS hydraulic line to pass directly through a panel while providing a perpendicular ORFS T-branch, optimizing space and reducing fitting count.
