11mm Ferrules | McMaster-Carr

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.

ISO and DIN sleeves meet international dimensional standards.

Nuts for Nickel-Plated Brass Compression Fittings for Copper Tubing

Nut

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 Compression Fittings for Steel Tubing

For Use With: Inch: Air, Hydraulic Fluid, Water
Metric: Hydraulic Fluid
Temperature Range: See table
Tubing: Inch: Use with welded steel
Metric: Use with seamless steel
Specifications Met: Inch: SAE J514
Metric: ISO 8434, DIN 2353

Use these sleeves with compression nuts and fittings, sometimes called bite fittings, to create a strong seal on steel tubing. They are also known as ferrules.

Zinc-plated steel sleeves have fair corrosion resistance.

ISO 8434 (formerly DIN 2353) sleeves meet international standards for tube fitting pressures.

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.
