When deciding which type of copper pipe to use for your AC system, consider the size and layout of your system, as well as the accessibility of the installation area. For small to medium-sized systems, soft copper is often the best choice. For larger systems, rigid copper is a better option. Ultimately, both types of copper pipes are excellent choices for AC systems, but it's important to choose the right type for your specific needs to ensure a successful installation and efficient operation.

Copper pipe and copper tube are often used interchangeably, but they are actually two different types of copper products. Copper pipe refers to a cylindrical shape that is generally used for plumbing and water supply systems.

• In air conditioning and refrigeration systems, copper tube is the preferred choice because of its ability to withstand high pressures and temperatures.
• When it comes to plumbing, copper pipe is the preferred choice due to its ease of installation and compatibility with fittings and valves. Copper pipe is also easier to cut and bend than copper tube, making it a more versatile option for plumbing applications.

Type K, L, or M copper tubing is generally the pipe type used for gas pipelines. These copper tubing varieties are stronger and thicker than other varieties of copper pipes, making them suitable for use with propane and natural gas.

• Due to its strength and thickness, Type K copper tubing is perfect for underground gas lines and substantial residential or commercial gas pipelines.
• Although slightly thinner than type K, type L copper tubing is still strong enough for the majority of residential and commercial gas pipelines. It is simple to bend and shape, and is frequently used for interior gas lines.
• The thinnest type of copper pipe is Type M, which is mainly used for small industrial and residential gas pipeline uses.
• The installation and testing of copper pipes and fittings used in gas pipelines must be done properly to ensure their reliability and safety.
