Sleeves 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 sleeves with a nut and fitting to provide a tight metal-to-metal seal on aluminum tubing that is flared to 37°. Sleeves are aluminum, which is lightweight with good corrosion resistance. They are also known as ferrules
