How do you measure copper pipe size?

How do you read copper fittings?

The proper way to read a copper tee is Side x Side x Center (Top). For example, a 3/4″ x 1/2″ x 1″ copper tee fitting is the same as 1/2″ x 3/4″ x 1″.

Fittings can be soldered or threaded onto the pipe ends.

### What is the outside diameter of copper pipe?

What size are most copper water pipes?

½ and ¾ inches
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. Type M ¾ inch measures 0.032” in wall thickness while type L ¾ measures 0.045”.

How is copper tee measured?

For example if a Tee is 3/4″ X 3/4″ X 1/2″, then the left inside diameter is 3/4″, the right inside diameter is 3/4″ and the top inside diameter part is 1/2″.
