Sleeves for Precision 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: -420° to 1200° F
- Tubing: Use with seamless or welded 304 or 316 stainless steel that meets ASTM A213, ASTM A249, or ASTM A269
- Compatible With: Parker CPI
Use these sleeves with precision compression nuts and fittings to create a strong seal on stainless steel tubing. Made to tighter tolerances than other sleeves, these are designed for high-precision applications. Sleeves are 316 stainless steel for excellent corrosion resistance. They are also known as ferrules.

Sleeves for Vibration-Resistant Compression Fittings for Copper Tubing
- For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Hydraulic Fluid, Lubricants, Mineral Oil, Water
- Temperature Range: -30° to 270° F, except fluoroelastomer rubber sleeves are -15° to 450° F
- Tubing: Use with copper
Use these sleeves with vibration-resistant compression nuts and fittings. They are rubber instead of metal, so they cushion the tubing and absorb vibration while creating a tight seal. They are also known as ferrules.

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.
Acetal sleeves won’t damage tubing.

Sleeves for Quick-Assembly Brass
Compression Tube Fittings for Air and Water
- Temperature Range: 0° to 150° F
- Tubing: Acetal plastic sleeves: Use with (firm or hard) polyethylene plastic or polypropylene plastic
Brass sleeves: Use with (firm or hard) nylon plastic, polyethylene plastic or polypropylene plastic
Use these to replace a damaged sleeve (ferrule) in quick-assembly brass compression nuts.
Brass sleeves have better durability than plastic sleeves.
