Sleeves for 37° Flared Fittings for Stainless Steel Tubing
- For Use With: Air, Hydraulic Fluid, Isopropyl Alcohol, Natural Gas, Phosphoric Acid, Water
- Temperature Range: -420° to 1,200° F
- Tubing: Use with seamless or welded 304 or 316 stainless steel that meets ASTM A213, ASTM A249, or ASTM A269
- Specifications Met: ISO 8434, SAE J514
Use these sleeves with a nut and fitting to provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°. Sleeves are 316 stainless steel for excellent corrosion resistance. They are also known as ferrules.

Sleeves 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 sleeves with precision AN nuts and fittings to provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°. They are also known as ferrules.
304 stainless steel sleeves have very good corrosion resistance. 316 stainless steel sleeves have excellent corrosion resistance.
Nuts with Built-In Sleeve for Quick-Assembly
Compression Fittings for Copper Tubing
- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -65° to 250° F
- Tubing: Use with copper
Use these nuts with quick-assembly compression fittings to create a strong seal on copper tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation. Thread the nut onto the fitting, then insert the tubing and tighten the nut. They are brass for good corrosion resistance.
