Which type of tubing is the thinnest?

The thinnest type of tubing among the options provided is Type M. This classification indicates its wall thickness, which is lighter and thinner compared to Types K, L, and N. In plumbing and irrigation systems, Type M tubing is typically made from materials like copper or plastic, which allows for flexible applications where lower pressure is involved. Due to its thin walls, Type M is often more affordable and easier to handle than thicker tubing, making it suitable for various irrigation setups where high strength is not a critical requirement. The other types (K, L, N) have increased wall thicknesses based on their intended uses, providing higher pressure capabilities and durability but are not classified as the thinnest tubing available.
