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.

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).
