Adaptor - TEE - SAE Specification - JIC (M) x JIC (M) x JIC (M)

A TEE adaptor with JIC (M) x JIC (M) x JIC (M) threads is a specialized hydraulic fitting designed to connect three lines using SAE J514-compliant 37° flare fittings. Here's a detailed breakdown:

Adaptor - TEE - SAE JIC (M) x JIC (M) x JIC (M)

Thread Type: JIC (Joint Industry Council) Male

• Standard: SAE J514 / ISO 8434-2
• Thread Form: UNF (Unified National Fine)
• Sealing Method: 37° metal-to-metal flare
• Connection: Leak-free, reusable, and vibration-resistant
• Common Sizes: 1/8" to 2" (e.g., 7/16"-20 for 1/4", 9/16"-18 for 3/8")

Materials & Construction

• Material: Typically carbon steel, 316 stainless steel, or brass
• Finish: Often zinc-trivalent plated for corrosion resistance 
  1
• Manufacturing: Forged for strength and durability

Design & Use

• Shape: T-shaped fitting with all three ends having male JIC threads
• Use Case: Branching a hydraulic line into two directions or connecting three JIC hoses/tubes
• Applications:
  • Hydraulic systems
  • Fuel and oil lines
  • Industrial machinery
  • Agricultural and construction equipment

Installation Tips

• Ensure the flare seats cleanly against the female counterpart
• Do not use thread sealant—the seal is made by the flare, not the threads
• Tighten to the recommended torque to avoid leaks or damage
