Application Summary AI generated

This standard specifies the dimensions, tolerances, and marking requirements for 55-degree pipe threads where the seal is not achieved through the threads themselves. It is applied in mechanical and plumbing systems for low-pressure connections, such as water, gas, or air pipelines, where a separate sealing method like a gasket or O-ring is used. The standard ensures interchangeability and compatibility of threaded components in general engineering and industrial piping applications.
