ČSN EN ISO 6149-1

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 bar1)) 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.
