Copper Nickel Tubing Sizes – An Overview

Copper Nickel Tubing Sizes

Copper nickel tubing is widely used in many industries due to its strong performance and durability. It is also favored for its corrosion resistance and ability to weld. But before you purchase copper nickel tubing for your project, you need to know the different sizes available to make the right choice. Let’s look at the various sizes of copper-nickel tubing on the market today.

Types of Copper Nickel Tubing Sizes

The most common types of copper-nickel tubing come in two main sizes – Type K and Type L. Type K is thicker than type L and has a wall thickness that ranges from .040″ up to .120″. Type L is lighter than type K and has a wall thickness that ranges from .032″ up to .104″. Both types are available in diameters ranging from 1/4″ to 8″.

Another important size consideration when selecting copper nickel tubing is the length of the tube. This should be determined by considering how long you need each piece of tubing and whether it needs to be cut down further. The standard length for copper nickel tubes is 20 feet, but they can also be purchased in 5-foot increments up to 15 feet long if needed. The outer diameter (OD) of copper-nickel tubes should also be considered when selecting a size, as this will help ensure the tube fits appropriately with your application’s other components.

Finally, several different types of fittings are available for use with copper-nickel tubes, including elbows, tees, crosses, couplings, unions, adapters, reducers, caps, and plugs, among others. These fittings come in several different sizes, so selecting the correct size is important based on your specific needs and desired outcome. For example, if you’re looking for an elbow fitting, ensure it’s compatible with both ends of the tube before making your selection.


When it comes to choosing the right size of copper-nickel tubing for your project or application, several different factors must be taken into account, including type (K or L), length (standard lengths range from 5-20 feet), OD (outer diameter) as well as any necessary fittings if applicable (elbows, tees, etc.). Knowing all these details beforehand can help ensure that you select the right size tube for your needs while avoiding any costly mistakes due to improper sizing down the road. With this knowledge in hand now, you can confidently buy your next batch of copper-nickel tubing, knowing that it will fit perfectly within your project!
