This document specifies dimensions for metric ports for use with the adjustable and non-adjustable stud ends as described in ISO61492 and ISO61493.
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 40MPa (400bar) for adjustable stud ends. The permissible working pressure depends upon port size, materials, design, working conditions, application, etc. See ISO61492 and ISO61493 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 = 105Pa; 1MPa=1N/mm2.
