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 Compression Fittings for Copper Tubing
- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -65° to 200° F, except metric fittings are -40° to 250° F
- Tubing: Use with copper
- Specifications Met: UL listed, except for metric fittings

Nuts for Nickel-Plated Brass Compression Fittings for Copper Tubing
- For Use With: Air, Cutting Oil, Diesel Fuel, Ethyl Alcohol, Fuel Oil, Gasoline, Hydraulic Fluid, Isopropyl Alcohol, Lubricants, Mineral Oil, Natural Gas, Steam, Water
- Temperature Range: -75° to 550° F
- Tubing: Use with copper
- Specifications Met: DIN 3870
Create a strong seal on copper tubing when you couple these nuts with compression sleeves and fittings. Made of nickel-plated brass, they resist corrosion better than plain brass. All meet DIN 3870, which is an international standard for tube fitting dimensions.

Sleeves for 37° Flared Fittings for Steel Tubing
- For Use With: Air, Fuel Oil, Hydraulic Fluid, Mineral Oil
- Temp. Range: -60° to 400° F
- Tubing: Use with seamless steel
- Specifications Met: SAE J514
Use these sleeves with a nut and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°. Sleeves are zinc-plated steel for fair corrosion resistance. They are also known as ferrules.
Inch × metric sleeve adapters convert the fitting from inch to metric.
