What is the difference between Type L and Type M copper pipe?
The key difference between types L and M is their pressure rating and wall thickness. The most common copper pipe sizes are ½ and ¾ inches. Type M ½ inch measures 0.028” in wall thickness whereas type L ½ inch measures 0.04” in wall thickness.
What is Type M and L copper?
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. The beefier Type L is often used underground, in hot water heating systems, for commercial plumbing and for gas line (where permitted).

Many engineers and field plumbers don’t realize that when you braze copper rather than solder copper joints, you reduce the pressure rating to that of annealed tube. A soldered four-inch Type L joint has a pressure rating of 440 psi.
What is the wall thickness of Type L copper?
2. Type L Copper Pipe. While not quite as thick as Type K, with a wall thickness of . 045 inches for a ¾-inch diameter pipe, it is still quite durable and can be used in many more ways.

What is Type L copper used for?
Type L Copper Pipe: Type L copper pipe is used for interior plumbing, fire protection, and some HVAC applications. It is available in rigid and flexible forms and can be used with sweat, compression, and flare fittings.
Can you bend Type L copper?
Type L copper is available in ‘hard’ drawn tube and ‘soft’ annealed tube. coils and is easily bent, a proper tube bending tool is required for bending.
Can you use Type L copper underground?
Type L Copper Pipe Type L is beefy enough to be used in underground applications but is often used to replace or repair water lines. It comes in both flexible rolls and rigid tubing, with the rigid tubing usually used for internal water piping and the flexible rolls used underground and outside the home.
