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
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.
