Part Number: 2704

37° JIC Bulkhead Run Tee

Product Overview

The Delphi Fittings Part 2704 is a 37° JIC Bulkhead Run Tee, uniquely designed to allow the straight-through ('run') portion of the tee to pass through and be secured to a panel or bulkhead. This fitting features male JIC 37° flare connections on all three ends (two on the run, with the run itself being the bulkhead mount, and one on the branch) and includes a locknut for panel installation. It is ideal for applications where a main hydraulic line needs to pass through a barrier while also providing a 90-degree branch connection on one side of the panel. Constructed from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 2704 ensures a robust and leak-free connection compliant with SAE J514 standards.

Key Features & Specifications

Material	High-Grade Carbon Steel
End Configurations (All 3 ends)	Male 37° JIC Flare (per SAE J514 / ISO 8434-2)
Body Style	Bulkhead Run Tee (one end of the 'run' is extended and threaded for bulkhead mounting) with integral hex features and a separate locknut. The branch is at 90° to the run.
Sealing Mechanism	JIC Ends: Metal-to-metal seal on the 37° flare cones with mating female JIC swivel nuts/flared tubes. Bulkhead Seal: Relies on the locknut compressing the fitting shoulder (or a surface on the run) against the panel. For enhanced environmental sealing, an appropriate flat washer or sealant may be used by the user.
Corrosion Protection	Standard Zinc Plating
Included Component	Locknut for the bulkhead run end (e.g., Part #306 JIC Bulkhead Locknut).
Primary Function	To provide a three-way JIC connection where the straight-through 'run' passes through and is secured to a panel or bulkhead, with a branch T-off on one side of the panel.
Working Pressure	Suitable for high-pressure hydraulic applications. Specific ratings vary by size.

Note: The fitting includes a corresponding locknut for the bulkhead run. For unlisted sizes or specific requirements, please contact our sales team.

Applications

The Part 2704 JIC Bulkhead Run Tee is versatile for applications such as:

Routing a primary hydraulic line through an equipment wall, panel, or chassis while simultaneously providing a 90-degree branch connection on one side.
Creating a T-junction where the main flow passes directly through a barrier, and a secondary line branches off from the run.
Commonly used in control systems, vehicle hydraulics, agricultural machinery, and industrial equipment where efficient space utilization, secure panel mounting, and a T-branch from a bulkhead line are required.
Facilitating organized line management by providing a fixed point for the run and branch connections at the panel interface.

Installation & Usage Guidelines

Drill or punch an appropriately sized hole in the panel or bulkhead 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 to prevent rotation during tightening.
Inspect all JIC flare ends and the mating female JIC sealing surfaces (cone inside the swivel nut) for cleanliness and any damage.
Connect the male JIC ends of the tee (both run ends and the branch end) to the female JIC swivel nuts on the hydraulic hoses or tubes. Apply a light coat of system-compatible lubricant (e.g., hydraulic oil) to the threads of the female swivel nuts (not the flare sealing surfaces) to ensure smooth tightening and prevent galling.
Tighten each JIC nut to the manufacturer's recommended torque or by using the "Flats From Wrench Resistance" (FFWR) method.
No thread sealant is used on JIC flare connections, as the seal is metal-to-metal on the flare.

Why Choose Delphi Fittings Part 2704?

Efficient Line Routing & Branching: Allows a main hydraulic line to pass directly through a panel while providing a perpendicular T-branch, optimizing space and reducing the need for additional fittings.
Reliable JIC Sealing: All three ports utilize the industry-proven SAE J514 37° flare metal-to-metal seal, ensuring high-pressure integrity and leak resistance.
Secure Panel Mounting: Includes a locknut for stable and robust installation of the run-through portion, providing a fixed T-junction at the panel.
Durable Construction: Manufactured from high-grade carbon steel for strength and longevity, with standard zinc plating for effective corrosion protection.
Standard Compliance: Adheres to SAE J514 / ISO 8434-2 standards, ensuring compatibility and interchangeability with other standard JIC components.
Quality Manufacturing: Produced under Delphi Fittings' rigorous ISO 9001:2015 certified quality management system.
