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.
