Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Nuts for 37° Flared Fittings for Aluminum Tubing
- For Use With: Air, Coolant, Gasoline, Hydraulic Fluid, Water
- Temperature Range: -60° to 350° F
- Tubing: Use with seamless aluminum
Use these nuts with a sleeve and fitting to provide a tight metal-to-metal seal on aluminum tubing that is flared to 37°. Nuts are aluminum, which is lightweight with good corrosion resistance.
