Metric Tubing Wall Thickness

Tubing Installation

When bending tubing, it is important to allow a sufficient

length of straight tubing between the shoulder of the tube

fitting and the bend. ( See Figure 2)

Tables #4 and #5 specify the minimum required lengths for

straight tubing leading into a tube fitting for each tubing OD

and bend radius.
