About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

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 High-Pressure Compression Fittings for Steel Tubing

For Use With: Hydraulic Fluid
Temperature Range: -75° to 750° F
Tubing: Use with seamless steel
Specifications Met: ISO 8434, DIN 2353

Use these sleeves—also known as ferrules—with high-pressure compression nuts and fittings. They withstand about twice as much pressure as sleeves for standard compression fittings, so they’re good for hydraulic power applications. These sleeves bite into the steel tubing as you tighten the nut, creating a strong seal. All meet ISO 8434 (formerly DIN 2353), which is an international standard for tube fitting pressures.

Front and Back Sleeves for Yor-Lok Fittings for Steel Tubing

For Use With: Air, Mineral Oil, Fuel Oil, Gasoline, Diesel Fuel, Cutting Oil, Hydraulic Fluid
Temperature Range: -20° to 800° F
Tubing: Use with seamless steel
Specifications Met: ASME B31.3
Compatible With: Let-Lok, Parker A-Lok, Swagelok®

Use these sleeves with Yor-Lok nuts and fittings to create an extra-strong seal on steel tubing. They are also known as ferrules.

Zinc-plated steel sleeves have fair corrosion resistance. 316 stainless steel sleeves have excellent corrosion resistance.

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.
