Save time installing sleeves and nuts—these sets come oriented in the correct direction and order on a dispenser. To install them, slide off a set and place it on your tubing. Each front sleeve, back sleeve, and nut is made of 316 stainless steel for excellent corrosion resistance. Five sets of sleeves and nuts come on each dispenser. Sleeves are also known as ferrules.

Nuts for Compression Fittings for Copper Tubing
Use these nuts with compression sleeves and fittings to create a strong seal on copper tubing. They are brass for good corrosion resistance.
Long nuts support more of the tube’s surface area than short nuts for a strong grip in high-vibration applications.
- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -65° to 250° F, except metric fittings are -40° to 250° F
- Tubing: Use with copper
- Specifications Met: UL listed, except for metric fittings
