THREAD DIMENSIONS

■ ■ Measure the tube O.D. and the male compression thread O.D. ■ ■ Measure the tube O.D. and the size of the wrench required for the tube nut. ■ ■ Measure the O.D. of the compression thread and the I.D. of the fitting body where the tubing will be seated.

To identify Metric DIN 2353 threads, you can first refer to the tube nut, if it is available, to read the fitting size and series that is stamped onto the nut. If no nut is available, or no size is stamped, then you can identify the fitting size by using the table provided below and one of the following measurements:
