DELPHI FITTINGS
Part Number: 2703
37° JIC Bulkhead Branch Tee
Product Overview
The Delphi Fittings Part 2703 is a 37° JIC Bulkhead Branch Tee. This specialized fitting allows one of the branch connections of the tee to pass through a panel or bulkhead, providing a secure mounting point while enabling a three-way JIC connection. It typically features male JIC 37° flare connections on all three ends (two on the run, 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 lines. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 2703 is built for reliability in demanding hydraulic systems and conforms to 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 Branch Tee (one branch end designed for bulkhead mounting) with integral hex features and a separate locknut. |
| 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 against the panel for the bulkhead branch. For enhanced environmental sealing, an appropriate flat washer or sealant may be considered by the user. |
| Corrosion Protection | Standard Zinc Plating |
| Included Component | Locknut for the bulkhead branch end (e.g., Part #306 JIC Bulkhead Locknut). |
| Primary Function | To provide a three-way JIC connection where one branch passes through and is secured to a panel or bulkhead. |
| Working Pressure | Suitable for high-pressure hydraulic applications. Specific ratings vary by size. |

Note: The fitting includes a corresponding locknut for the bulkhead branch. For unlisted sizes or specific requirements, please contact our sales team.
Applications
The Part 2703 JIC Bulkhead Branch Tee is widely used for:
- Creating a T-junction in a hydraulic circuit where one line needs to pass through an equipment wall, chassis, or panel, for example, to connect to a component mounted on the other side or to tap into a line from outside an enclosure.
- Providing a fixed and secure branching point on a panel for hydraulic hoses or tubes, ensuring organized and stable line routing.
- Applications in mobile machinery, agricultural equipment, control panels, industrial equipment, and any system requiring a robust, panel-mounted tee connection for JIC lines.
- Used when a fluid line needs to be split or merged at a bulkhead interface, facilitating system design and component integration.
Installation & Usage Guidelines
- Prepare the panel by drilling or punching an appropriately sized hole for the bulkhead branch of the tee.
- Ensure the panel surface around the hole is clean and flat to facilitate a secure mount.
- 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 firmly against the panel surface. Use a wrench on the fitting's hex body to prevent the tee from rotating during tightening.
- Inspect all JIC flare ends and the mating female JIC sealing surfaces (cone inside the swivel nut) for cleanliness and any signs of damage before assembly.
- Connect the male JIC ends of the tee to the female JIC swivel nuts on the hydraulic hoses or tubes. It is recommended to apply a light coat of system-compatible lubricant (such as hydraulic oil) to the threads of the female swivel nuts (avoiding the flare sealing surfaces) to ensure smooth tightening and prevent thread galling.
- Tighten each JIC nut to the manufacturer's specified torque or by using the "Flats From Wrench Resistance" (FFWR) method.
- No thread sealant is necessary on JIC flare connections, as the seal is achieved by the metal-to-metal contact on the flare.
