Dimensional Range Table
In plumbing and HVAC standards, copper tubing is commonly classified into three main types based on wall thickness: Type K, Type L, and Type M.
Type K: Has the thickest wall. It is the strongest and most durable, primarily used for underground burial, high-pressure applications, and where the highest level of protection is required.
Type L: Has a medium wall thickness. It is the most common and versatile type, widely used for residential and commercial water supply lines (hot and cold) and for many HVAC applications.
Type M: Has the thinnest wall. It is suitable for above-ground, low-pressure residential water supply lines and some drainage applications, offering a cost-effective solution where conditions allow.
The outside diameter (OD) is the same for all three types within a given nominal size. The difference lies in the inner diameter (ID), which decreases as the wall gets thicker.
| Nominal Size (inches) | Type K | Type L | Type M |
|---|---|---|---|
| Outside Diameter (OD) | Same for all types | ||
| Wall Thickness | Thickest | Medium | Thinnest |
| Inside Diameter (ID) | Smallest | Medium | Largest |
