DELPHI FITTINGS
Part Number: 2406
37° Female JIC x JIC Male Tube Expander / Reducer
Product Overview
The Delphi Fittings Part 2406 is a versatile straight adapter designed to connect JIC (Joint Industry Council) 37° flare fittings of different sizes. This fitting typically features a female JIC 37° flare swivel nut on one end and a male JIC 37° flare on the other, with the two ends being of different dash sizes to achieve either a reduction or an expansion in line size. This capability is essential for integrating components or tubing with varying JIC dimensions within a hydraulic system. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 2406 expander/reducer provides a reliable, metal-to-metal seal characteristic of JIC connections, ensuring system integrity across different line sizes.

Note: JIC sizes are denoted by dash numbers or their UNF thread size. Always verify the specific sizes needed for your application. For unlisted size combinations, please contact our sales team.
Applications
The Part 2406 JIC Expander/Reducer is crucial for adapting line sizes within JIC systems:
- Connecting a hydraulic hose with a female JIC swivel of one size to a flared tube or male JIC fitting of a different size.
- Stepping up or stepping down the size of a hydraulic line at a connection point.
- Integrating components with varying JIC port sizes into a cohesive system.
- Use in mobile equipment, industrial machinery, agricultural vehicles, and any application utilizing JIC 37° flare connections where size changes are necessary.
Installation & Usage Guidelines
- Ensure all JIC flare sealing surfaces (male flare nose and female cone seat) on the adapter and mating fittings are clean, smooth, and free from any damage or debris.
- Align the female JIC swivel nut end of the adapter with the mating male JIC fitting. Ensure the threads engage smoothly. Tighten the swivel nut by hand until snug.
- Align the male JIC flare end of the adapter with the mating female JIC swivel fitting or flared tube assembly. Thread the mating swivel nut onto the adapter's male JIC end by hand until snug.
- Use two wrenches for final tightening: one to hold the adapter body (or the non-swiveling mating part) and one to tighten the JIC swivel nuts to the recommended torque. Do not overtighten.
- No thread sealant is required for JIC flare connections.
