The Hypodermic Tubing tables on this page have been revised to address the inconsistency of past "standards" which vary by vendor. MicroGroup has attempted to meet as many of these old varied standards as possible in these new tables. Please verify your older prints. Although every effort has been made to ensure accuracy, no guarantee is granted or implied. Unlike other tubing and pipe sizes, hypodermic tubing is specified by a gauge number that determines OD and ID of the tube, not the wall thickness.
