ISO 9413:2019

Tyre valves - Dimensions and designation

This document defines the essential dimensions and the designation of tube valves and tubeless valves.

Annex B gives the correspondence between ISO designations and the designations established by:

— TRA (Tire and Rim Association Inc.);

— ETRTO (European Tyre and Rim Technical Organisation);

— JATMA (The Japan Automotive Tyre Manufacturer's Association, Inc.).

In the remainder of this document, all the dimensions are given at their nominal value except in cases where the tolerances are indicated.

The threaded length of valve stems for which no thread length is specified is the maximum possible length.

NOTE The drawings for valves are not all at the same scale.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.
