Nuts for 37° Flared Fittings for Copper Tubing
- For Use With: Air, Fuel Oil, Mineral Oil, Water
- Temperature Range: -40° to 400° F
- Tubing: Use with seamless copper
- Specifications Met: ISO 8434, MIL-F-18866, SAE J514
Use these nuts with a sleeve and fitting to provide a tight metal-to-metal seal on copper tubing that is flared to 37°. They are brass for good corrosion resistance.
