Connections for hydraulic fluid power and general use - Ports and stud ends with ISO 261 metric threads and O-ring sealing - Part 1: Ports with truncated housing for O-ring seal (ISO 6149-1:2022)

This document specifies dimensions for metric ports for use with the adjustable and non-adjustable stud ends as described in ISO 6149‑2 and ISO 6149‑3.
Ports in accordance with this document can be used at working pressures up to 63 MPa (630 bar[1]) for non-adjustable stud ends and 40 MPa (400 bar) for adjustable stud ends. The permissible working pressure depends upon port size, materials, design, working conditions, application, etc. See ISO 6149‑2 and ISO 6149‑3 for pressure ratings.
NOTE      The Introduction of this document gives recommendations for ports and stud ends to be used for new designs in hydraulic fluid power applications.
[1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.

Dieses Dokument legt Maße für Einschraublöcher mit metrischem Gewinde für richtungseinstellbare und nicht richtungseinstellbare Einschraubzapfen nach ISO 6149 2 und ISO 6149 3 fest.
Einschraublöcher nach diesem Dokument können bei Arbeitsdrücken bis 63 MPa (630 bar ) mit nicht richtungseinstellbaren Einschraubzapfen und bis 40 MPa (400 bar) mit richtungseinstellbaren Einschraubzapfen verwendet werden. Der zulässige Arbeitsdruck ist abhängig von der Größe des Einschraubloches, den Werkstoffen, Konstruktion, Betriebsbedingungen, Anwendungsfall usw. Druckstufen siehe ISO 6149 2 und ISO 6149 3.
ANMERKUNG   Die Einleitung dieses Dokuments enthält Empfehlungen für die bei Neukonstruktionen in hydraulischen Anlagen der Fluidtechnik zu verwendenden Einschraublöcher und Einschraubzapfen.

Le présent document spécifie les dimensions des orifices métriques pour utilisation avec les éléments mâles orientables et non orientables tels que décrits dans l’ISO 6149-2 et l’ISO 6149-3.
Les orifices conformes au présent document peuvent être utilisés jusqu'à des pressions de travail de 63 MPa (630 bar[1]) pour les éléments mâles non orientables et jusqu’à 40 MPa (400 bar) pour les éléments mâles orientables. La pression de travail admissible dépend de la dimension de l'orifice, des matériaux, de la conception, des conditions de travail, de l'utilisation, etc. Voir l'ISO 6149-2 et l’ISO 6149-3 pour les pressions de travail.
NOTE         L'Introduction du présent document donne des recommandations pour les orifices et les éléments mâles à utiliser pour de nouvelles conceptions dans des applications de transmissions hydrauliques.

Introduction

In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure

within an enclosed circuit. In general applications, a fluid (liquid or gas) may be conveyed under

pressure.

Components are connected through their threaded ports by fluid conductor connectors to tubes and

pipes or to hose connectors and hoses.

Ports are an integral part of fluid power components, i.e. pumps, motors, valves, cylinders.

For threaded ports and stud ends specified in new designs in hydraulic fluid power applications,

ISO/TC 131/SC 4 recommends that the ISO 6149 series be used because these International Standards

specify ports and stud ends with metric threads and O-ring sealing and because the subcommittee

would like to help users by recommending o
