Nuts with Built-In Sleeve for Quick-Assembly
Compression Fittings for Copper Tubing
- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -65° to 250° F
- Tubing: Use with copper
Use these nuts with quick-assembly compression fittings to create a strong seal on copper tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation. Thread the nut onto the fitting, then insert the tubing and tighten the nut. They are brass for good corrosion resistance.
