This International Standard specifies dimensions and performance requirements for ports and stud ends with parallel threads for pneumatic fluid power applications. It specifies reusable, positively retained seals for leak-free connections, for use at pressures from - 0,09 MPa (- 0,9 bar) up to 1,6 MPa (16 bar). Only this International Standard is applicable for threaded ports and stud ends specified in new designs in pneumatic fluid power applications. Ports and stud ends conforming to this International Standard are not intended to connect with ports and stud ends that conform to ISO 1179 or threads that conform to ISO 7-1. note: 1) 1 bar = 0,1 MPa = 10Pa; 1 MPa = 1 N/mm
