Nuts for 45° Flared Fittings for Copper and Brass Tubing
(A) Short Nut
(B) Short Nut
(A) Long Nut
- For Use With: Cutting Oil, Fuel Oil, Refrigerant, Mineral Oil, Diesel Fuel, Water, Air
- Temperature Range: -65° to 250° F
- Tubing: Use with seamless brass and copper that meets ASTM B280
- Specifications Met: SAE J512, SAE J513, UL Listed
Use these nuts with 45° flared tube fittings to provide a tight metal-to-metal seal on flared copper and brass tubing. Nuts are brass for good corrosion resistance. They don’t require a sleeve, which makes for a fast, convenient installation.
Long nuts support more of the tube’s surface area than short nuts for a strong grip in high-vibration applications.
