Small medical gas cylinders — Pin-index yoke-type valve connections
This document is applicable to pin-index yoke-type valve connections for medical gas cylinders, with a working pressure up to a maximum of 200 bar or test pressure up to a maximum of 300 bar, or both.
NOTE 1 This type of connection is primarily used for small cylinders (5 l or below).
NOTE 2 In this document the unit bar is used, due to its universal use in the field of technical gases. It should, however, be noted that bar is not an SI unit, and that the corresponding SI unit for pressure is Pa (1 bar = 105 Pa = 105 N/m2).
This document specifies:
— basic dimensions;
— requirements for alternative designs of the yoke-type valve connections;
— dimensions and positions for the holes and pins for the outlet connections.
It also specifies the dimensions and positions for the holes and pins for the outlet connections for gases and gas mixtures.

Frequently Asked Questions about ISO 407:2023
When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.
Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
If you have an extensive portfolio of standards, we recommend using a professional standards management tool. With effects 2.0, you can manage your standards centrally and efficiently. You can optimise your procurement processes and benefit from an integrated information and subscription service. This ensures you are always up to date and never miss any relevant developments.
