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 sleeves are -15° to 450° F
- Tubing: Use with copper
The sleeve (ferrule) in these fittings is rubber instead of metal, so it cushions the tubing and absorbs vibration while creating a tight seal. The sleeve aligns the tubing during installation. Fittings come with a nut and a sleeve. They are also known as flareless fittings. They are brass for good corrosion resistance.
NPTF (Dryseal) threads are compatible with NPT threads.

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.
