Copper Tube Square Cheap 99% Pure Copper Nickel Pipe 20mm 25mm Copper Tubes 3/8 Brass Tube Pipe

Copper pipes are commonly used in the construction industry for residential water supply lines and sometimes for drain and vent lines. Copper pipes can be manufactured as soft or rigid copper and they offer excellent corrosion resistance and reliable connections. While flexible PEX (cross-linked polyethylene) is now the more common choice for new installation and upgrades, copper pipe still has its place.

It is considered a sturdier building material that has a longer lifespan—lasting up to 70 years. However, copper is about 60 percent more expensive than PEX, and it can be susceptible to cracking if the water inside the pipes is subject to freezing temperatures.

The three most common types of copper pipe used in residential and commercial construction are Type K, Type L, and Type M. A fourth type, used for drain-waste-vent, or DWV, piping, is found most often in some older homes. Below, we'll discuss how to choose the right copper pipe for your application.
