DELPHI FITTINGS
Part Number: 2700
37° JIC Bulkhead Straight Union
Product Overview
The Delphi Fittings Part 2700 is a 37° JIC Bulkhead Straight Union designed for passing hydraulic lines through panels, bulkheads, or plates. It features male JIC 37° flare connections on both ends for connecting to female JIC swivel fittings or flared tubes. A locknut is included to secure the fitting to the panel, ensuring a stable and sealed pass-through. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, this fitting allows for a continuous JIC connection while providing a secure mounting point.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration | Male 37° JIC Flare (per SAE J514 / ISO 8434-2) |
| End 2 Configuration | Male 37° JIC Flare (per SAE J514 / ISO 8434-2) |
| Body Style | Straight Bulkhead Union with integral hex and 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: Typically relies on the locknut compressing the fitting shoulder against the panel; an additional O-ring or sealant may be used on the panel surface for enhanced sealing depending on the application (not supplied standard with the fitting itself for this purpose unless specified). |
| Corrosion Protection | Standard Zinc Plating |
| Included Component | Locknut (e.g., Part #306 JIC Bulkhead Locknut) |
| Primary Function | To create a straight, through-panel connection for JIC hydraulic lines, secured by a locknut. |
| Working Pressure | Suitable for high-pressure hydraulic applications. Specific ratings vary by size. |

Applications
The Part 2700 JIC Bulkhead Straight Union is essential for:
- Passing hydraulic lines through machine walls, vehicle chassis, control panels, or equipment enclosures.
- Providing a fixed connection point on a panel for hydraulic hoses or tubes.
- Maintaining hydraulic circuit integrity when lines need to traverse barriers.
- Used in mobile equipment, industrial machinery, agricultural vehicles, and any application requiring neat and secure routing of JIC hydraulic lines through a flat surface.
Installation & Usage Guidelines
- Drill or punch an appropriately sized hole in the panel or bulkhead for the fitting body.
- Ensure the panel surface around the hole is clean and flat to facilitate a good seal if one is intended at the panel.
- Insert the threaded body of the bulkhead union (the end opposite the hex shoulder) through the hole from one side.
- Slide the locknut over the protruding threads on the other side of the panel and tighten it securely against the panel surface. Use a wrench on the fitting's hex shoulder to prevent it from turning while tightening the locknut.
- Ensure all JIC flare ends and mating female JIC sealing surfaces (cone inside the swivel nut) are clean, undamaged, and free of contaminants.
- Connect the male JIC ends of the bulkhead union to the female JIC swivel nuts on the hoses or tubes. It is good practice to apply a light coat of system-compatible lubricant (like 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 using the "Flats From Wrench Resistance" (FFWR) method.
- No thread sealant is used on JIC flare connections. If sealing between the fitting shoulder/locknut and the panel is critical for environmental protection, consider using a flat gasket or appropriate sealant compatible with the panel material and fluid; this is application-dependent and not standard with the fitting.
