Sleeves for High-Pressure Compression
Fittings for Stainless Steel Tubing

- For Use With: Air, Cutting Oil, Ethyl Alcohol, Fuel Oil, Gasoline, Hydraulic Fluid, Isopropyl Alcohol, Mineral Oil, Natural Gas, Steam, Water
- Temperature Range: -75° to 750° F
- Tubing: Use with seamless 304 or 316/316L/316Ti stainless steel that meets DIN EN 10216-5 or DIN EN 10305-1
- Specifications Met: DIN 2353, ISO 8434
When used with high-pressure compression fittings and nuts, these sleeves bite into stainless steel tubing to form a strong seal. Made from 316 stainless steel, they won’t corrode from water, chemicals, or salt spray. These nuts meet ISO 8434 (formerly DIN 2353), which is an international standard for tube fitting dimensions and materials.

Sleeves for Brass Compression Tube Fittings for Air and Water

- For Use With: Air, Lubricated Air, Water
- Temperature Range: See table
- Tubing: Use with firm or hard (Durometer 1A-95A or-Rockwell 15T 1-15T 60) nylon plastic, polyethylene plastic, polypropylene plastic or polyurethane rubber
- Specifications Met: SAE J512, except metric sizes
Use these sleeves with brass compression nuts and fittings to create a seal on plastic and rubber tubing.
Brass sleeves work best with nylon tubing. When using these sleeves with soft tubing such as polyethylene, polypropylene, and polyurethane tubing, you should use a tube support (not included).
