Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
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.
304 stainless steel nuts have very good corrosion resistance.
