The ISO specification was for metric sizes only and did not satisfy the concerns of the C1 committee regarding the smaller size torque limitations.1. SCOPE This part defines performance requirements, dimensions, and design

7、s for 2 through 32 internal and external hex port plugs for use in SAE J1926-1 ports. Testing and usage through many years confirm the performance requirements of port plugs made from carbon steel. The port plugs were specified in SAE J514 without any performance requirements. They have been develop

8、ed and tested to gain a 4:1 working pressure rating for industrial applications. In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under pressure within an enclosed circuit. In general applications, a fluid may be conveyed under pressure. Components are conn

9、ected through their threaded ports by stud ends on fluid conductor fittings to tubes and pipes or to hose fittings and hoses. For threaded ports and stud ends specified in new designs in hydraulic fluid power applications, only ISO 6149 shall be used. Threaded ports and stud ends in accordance with

10、ISO 1179, ISO 9974, and ISO 11926 are not to be used in new designs in hydraulic fluid power applications. Conformance to the dimensional information in this part of SAE J1926 does not guarantee rated performance. Each manufacturer should perform testing according to the specification contained in t

11、his part of SAE J1926 to assure that components comply with the performance ratings. 2.
