When to use Type L and Type M copper pipe sizes. Type L copper pipe is recommended where you need strength and protection. But for normal “in the wall” household plumbing, Type M copper pipe is just fine.
What’s the difference between L and M copper pipe?

What are the 4 types of pipes?
There are five main types of plumbing pipe materials that are still in use today: copper, galvanized steel, polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), and cross-linked polyethylene (PEX).
What is the difference between type L and K copper?
Each type represents a series of sizes with different wall thicknesses. Type K tube has thicker walls than Type L tube, and Type L walls are thicker than Type M, for any given diameter. All inside diameters depend on tube size and wall thickness.
Which is stronger L or M copper?
However, in certain jurisdictions, you can find that they require type L pipes to be used. Water pressure is the primary cause because some municipal water sources require high water pressure to meet the demand. The thicker L copper pipes can withstand higher pressure than the M copper pipes.
What is type M copper used for?
Type M Copper Pipe: Type M copper pipe is thinner than both type K and L copper pipe. Sold in both rigid and flexible forms, Type M is used most commonly for heating water services and vacuum systems. It can be used with sweat, compression, and flare fittings.
What type copper pipe is used for water?
Green copper pipes, that is type K, are the only type suitable for burying underground. They’re generally used for supplying water into a house. Types L and M are the ideal pipes for supplying water throughout a home. Type L comes with thicker walls than type M.
What pipe is thicker L or M?
Differences Between Types M and L
The two most common sizes are half-inch and three-quarter-inch. Type M half-inch pipe has a wall thickness of 0.028 inches while type L is 0.040 inches. Type M three-quarter-inch pipe has a wall thickness of 0.032 inches and type L is 0.045 inches. Type L costs more than type M.
Can you heat copper with Type M?
Facts About Copper Pipe:
Type M is thin-wall copper pipe; Type L is thick-wall pipe. In some areas, Type M pipe isn’t allowed for delivering potable water, but it can be used for hot-water heating systems. Copper pipe is commonly available in diameters ranging from ½ inch to 2 inches.
What are the three types of pipes?

What is Type R copper tubing used for?
This type of copper is used in split-system HVAC units and heat pumps. They are easily flared for connections. Hardened copper tubing is used for water lines, commercial refrigeration and HVAC.
Can you bend type L copper?
First, traditional type L copper tubing can not be bent. If it is, it can break down and create micro-fractures, leading to leaks and catastrophic system vulnerabilities. Therefore, U.S. piping systems require an excess of joints and fittings, which leads us to the second reason.
What size is residential water line?
In most cases, the main pipeline from the street to your home is either 3/4 or 1 inch in diameter, supply branches use 3/4-inch-diameter pipe, and pipes for individual components are 1/2 inch.
