Part Number: 2603

37° JIC Male Union Tee

Product Overview

The Delphi Fittings Part 2603 is a 37° JIC Male Union Tee, designed for creating a 90-degree branch connection within a JIC (Joint Industry Council) 37° flare hydraulic system. This fitting features male JIC 37° flare ends on all three ports (run x run x branch). It allows for the connection of three female JIC swivel fittings or flared tubes of the same size, enabling the division of a single flow path into two, or the merging of two paths into one. The JIC connection provides a reliable metal-to-metal seal on the 37-degree flare cone, making this tee suitable for high-pressure applications. Manufactured from high-quality carbon steel and zinc-plated for corrosion resistance, the Part 2603 is a fundamental component for versatile plumbing in mobile equipment, industrial machinery, and various fluid power systems.

Note: JIC sizes are often denoted by dash numbers or their UNF thread size. Reducing JIC male union tees may also be available. For unlisted sizes or specific requirements, please contact our sales team.

Applications

The Part 2603 JIC Male Union Tee is widely used for:

Splitting a hydraulic line into two separate branches.
Combining two hydraulic lines into a single line.
Adding a port for gauges, sensors, or auxiliary equipment within a JIC system.
Creating manifold-like junctions in hydraulic circuits on mobile equipment, industrial machinery, and agricultural implements.
Applications requiring reliable, high-pressure, and reusable tee connections for JIC hoses or flared tubes.

Installation & Usage Guidelines

Ensure all male JIC flare ends of the tee and the mating female JIC seats (in swivel nuts or flared tube assemblies) are clean, undamaged, and free of contaminants.
Align the tee with the mating female JIC fittings.
Thread the female JIC swivel nuts onto each male JIC flare end of the tee by hand until finger tight. Ensure the 37° flare surfaces are correctly aligned and seat properly.
Use appropriate wrenches: one to hold the tee body steady (backup wrench) and one to tighten each JIC swivel nut to the recommended torque.
No thread sealant is required for JIC flare connections as the seal occurs on the metal-to-metal flare seat.
Properly orient the tee for the desired flow path before final tightening.
