Nuts for Precision AN 37° Flared Fittings for Stainless Steel Tubing

- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -320° to 1200° F
- Tubing: Use with seamless 304 or 316 stainless steel
- Specifications Met: See Table
Use these nuts with precision AN sleeves and fittings to provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°. The threads are Class 3B and adhere to tighter tolerances than other nuts. They are made to exact AS (formerly AN) specifications.
316 stainless steel nuts have excellent corrosion resistance.
