37° JIC SAE Flare Male Tube Union - Part 2403

Part Number: 2403

37° JIC SAE Flare Male Tube Union

Product Overview

The Delphi Fittings Part 2403 is a 37° JIC SAE Flare Male Tube Union, designed to create a secure, in-line connection between two flared tubes or two female JIC swivel fittings of the same size. This straight union features male JIC 37° flare ends on both sides. The JIC (Joint Industry Council) connection is a widely adopted standard in hydraulic systems, known for its reliability and reusability due to the metal-to-metal seal on the 37-degree flare cone. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 2403 union is ideal for high-pressure applications in mobile equipment, industrial machinery, and various fluid power systems.

Applications

The Part 2403 JIC Male Union is widely used for:

  • Joining two hydraulic hoses equipped with female JIC swivel nuts.
  • Connecting two sections of flared tubing in a straight line using JIC nuts and sleeves.
  • Extending existing JIC hydraulic lines.
  • Applications in mobile equipment (construction, agriculture), industrial machinery, material handling, and transportation hydraulics.
  • General high-pressure fluid transfer systems where reliable, reusable connections are required.

Installation & Usage Guidelines

  • Ensure both male JIC flare ends of the union and the mating female JIC seats (either in a swivel nut or a flared tube assembly) are clean, undamaged, and free of contaminants.
  • Align the union with the mating female JIC fittings.
  • Thread the female JIC swivel nuts onto the male JIC flare ends of the union by hand until finger tight. Ensure the 37° flare surfaces are correctly aligned and seat properly.
  • Use two wrenches: one to hold the union body steady (backup wrench) and one to tighten each JIC swivel nut to the recommended torque. Do not overtighten, as this can damage the flare.
  • No thread sealant is required for JIC flare connections as the seal occurs on the metal-to-metal flare seat.
