Gas cylinders. 17E and 25E taper threads for connection of valves to gas cylinders - Inspection gauges Ingestion-build-93833 If the number of pilots1 Scope This document specifies types, dimensions and principles of use of gauges, to be used in conjunction with the taper threads specified in ISO 113631 (i. e. 17E and 25E threads). It provides examples of calculations for thread gauge dimensions on the large end diameter (Annex A) and draws attention to the limitations of the gauging system specified (Annex B).
