Pneumatic fluid power — Push-in connectors for thermoplastic tubes

This document specifies the general requirements and test methods for the design and performance of push-in connectors for use with thermoplastic tubes with outside diameters (OD) from 3 mm to 16 mm including dimensions in inches. This document is intended to establish uniform methods of testing complete push-in connector assemblies as used in pneumatic fluid power applications. It is not applicable to air braking systems.

Transmissions pneumatiques — Raccords instantanés pour tubes thermoplastiques

Le présent document spécifie les exigences générales et les méthodes d'essai pour la conception et les performances des raccords instantanés destinés à être utilisés avec des tubes thermoplastiques de diamètre extérieur (DE) compris entre 3 mm et 16 mm inclus. Le présent document établit des méthodes d'essai uniformes de l'ensemble complet du raccord instantané, tel qu'il est utilisé dans les applications de transmissions pneumatiques. Elle ne s'applique pas aux systèmes de freinage à air.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso .org/

This document was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee
SC 4, Connectors and similar products and components.
This second edition cancels and replaces the first edition (ISO 14743:2004), which has been technically
revised. The main changes compared to the previous edition are as follows:
— new fitting size including inch dimensions has been added;
— new normative references have been added;
— updates on leakages performances and precisions have been added for cyclic endurance with
vibration.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/ members .html.
Introduction
In pneumatic fluid power systems, power is transmitted and controlled through air under pressure
within a circuit.
Components are connected through their ports by means of connectors (fittings) and conductors.
