Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
37° Flared Fittings for Aluminum Tubing
- For Use With: Air, Coolant, Gasoline, Hydraulic Fluid, Water
- Temperature Range: -60° to 400° F
- Tubing: Use with seamless aluminum
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings are aluminum, which is lightweight with good corrosion resistance. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
