Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
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
The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings. They are made to exact AS (formerly AN) specifications and provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
316 stainless steel fittings have excellent corrosion resistance.
Fittings that swivel until tightened have a built-in nut that rotates 360° for easy installation.
Fittings with female tube end have an internal flare that mates with the male tube end of another fitting.
