How do I determine the wall thickness on tubing?

Having the inside dimensions (ID) and the outside dimensions (OD) will allow you to figure out the wall thickness on the tubing. You would need to subtract the ID from the OD and then divide by two. This number is the wall thickness.

For example: Item# 59001 has an ID of 1/8" and an OD of 3/16". Subtract 3/16" - 1/8" = 1/16". Then divide 1/16" by 2 to get 1/32", which is the wall thickness.
