ISO 9413:1998

This International Standard 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 Tire and Rim Technical Organisation);
• JATMA (The Japan Automotive Tire Manufacturer's Association, Inc.).

For an intermediate period, corresponding references as given in annex B are permitted in place of ISO designations.

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

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

This International Standard does not specify requirements for the caps which equip the valves, nor do the caps appear in the figures.
