L vs M Copper Pipe: Difference and Comparison

L-pipe is used to transport gas and liquid. M-pipe has a larger interior diameter than L pipe, which makes it perfect for transporting large quantities of fluids when compared with smaller pipes like L or DWV piping systems.

While both pipes can be made from the same material (copper), L-pipe is much more rigid and cannot be bent or cut to size.

Key Takeaways

  1. L copper pipes have thicker walls, providing greater durability and a longer lifespan than M copper pipes.
  2. M copper pipes are more affordable due to their thinner walls, making them suitable for budget-conscious projects.
  3. L copper pipes are ideal for underground and outdoor use, while M copper pipes are commonly used for indoor water distribution.

L Copper Pipe vs M Copper Pipe

L copper pipes are the most common type of copper pipe used in residential and commercial plumbing applications. They are made from high-quality copper and have a wall thickness. M copper pipes are similar to L copper pipes in terms of their composition and manufacturing process. However, they have a slightly thinner wall thickness, which makes them more affordable than L copper pipes.

L Copper Pipe vs M Copper Pipe

L-pipe features an inside diameter between 36mm and 76mm. L-pipe is used to transport gas and liquid. L-pipe is used in residential applications because it’s easier for plumbers and homeowners to install and connect.

L-pipes can also be installed above the ground or below grade.

While M-pipe is made from a flexible metal called “copper” and can bend slightly, which means it’s perfect for transporting large quantities of fluids (like water).

M-pipes are available in a range of sizes from 25mm to 900mm.”M pipes require a vaulted installation that provides support from beneath (up inside of a concrete wall).

What is M Copper Pipe?

M pipes are larger in size and used for water lines or other large-volume piping systems. The larger sized pipe can be installed below grade because of their weight and strength.

M pipes are also easy for homeowners or professional plumbers to work on because they weigh less than the other types of piping.”

M pipes are easier to work with because they weigh less than the other types of piping.

It is also easy for homeowners or professional plumbers to install M pipes in tight spaces, which makes them more versatile and easier to use than L copper pipe.”

Some people don’t like working with M copper pipes because they are not as rigid. Another disadvantage that can be a problem for some people is the weight of them, which makes it more difficult to install larger sizes below grade.

Main Differences Between L and M Copper Pipe

  1. The size of L and M copper pipes is different: the inside diameter, outside diameter, and weight. L pipe weighs about 80 pounds per foot, whereas the M pipes weigh only 68 pounds per foot.
  2. L pipe ductile iron pipes are made with a seamless process that produces a pipe with no seam. M pipes are made by a continuous casting process, which produces seams on the inside and outside of the pipe.
  3. L copper tube has an additional benefit: it is classified as Type K for use in high-pressure applications where higher pressures can be expected to exist. M Copper Pipe does not have these benefits because it is not classified as Type K.
  4. M Copper Pipe has one advantage over L pipe, though: M pipes are easier to handle and can be installed with a smaller inside diameter, which may make them more cost-effective in some cases.
  5. L Copper Pipe: Type L has more material and can withstand higher pressures better than M copper tube. However, because it is heavier than M pipe and requires larger holes for installation, the cost may dictate whether this type is the best option.
