Sleeves for Compression Fittings for Stainless Steel Tubing

Use these sleeves with compression nuts and fittings to create a strong seal on stainless steel tubing. Sleeves are stainless steel for excellent corrosion resistance. They are also known as ferrules or rings.
For technical drawings and 3-D models, click on a part number.
- For Use With: Air, Hydraulic Fluid, Water
- Temperature Range: -420° to 1200° F
- Tubing: Use with seamless or welded 304 or 316 stainless steel that meets ASTM A269
- Specifications Met: SAE J514
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.
