Vacuum technology－Quick release couplings－Dimensions－Part 2：Screwed type

This document specifies dimensional requirements for quick-release couplings used in vacuum applications, focusing specifically on the threaded variant. It establishes precise geometric tolerances and interface dimensions to ensure interchangeability and compatibility across different components within vacuum systems. The scope addresses critical connection points where mechanical integrity and seal reliability are essential for maintaining system vacuum levels. By defining standardized thread profiles and mating dimensions, the text aims to facilitate consistent manufacturing and assembly practices. These specifications cover various key measurements necessary for the proper functioning of threaded coupling mechanisms in industrial and scientific settings. The information provided serves as a technical reference for designers, manufacturers, and quality control personnel engaged in the production and maintenance of vacuum equipment components. Adherence to these dimensional parameters helps prevent potential leakage issues and ensures safe operation under vacuum conditions.
