Can compression fittings be used on copper tubing?

Yes, always
Yes, but only for specific applications
No, they cannot be used
Only with special adapters

The correct answer is: No, they cannot be used

Compression fittings can indeed be used on copper tubing, making the choice indicating they cannot be used incorrect. Compression fittings are designed to create a secure, leak-proof connection by compressing a ring or ferrule onto the tubing when the nut is tightened. This method is commonly used with copper tubing in various plumbing and gas applications, which makes it crucial for fittings to be compatible with the metal properties of copper. In many instances, using compression fittings is actually preferred when connecting copper tubing because they do not require welding or soldering, which simplifies installation and repair efforts. This versatility in application reflects their acceptance in both residential and commercial settings. Understanding the range of applications for compression fittings is important. While there may be specific scenarios where types of fittings or methods might be more appropriate, the general application of compression fittings to copper is valid and permissible.
