Scope

This document specifies the dimensions and performance requirements of the air-operated cylindrical threaded ports and column ends. To ensure leak-free connections within a pressure range of -0.09 MPa to +1.6 MPa, it is required to use reusable, effectively pressure-retaining seals. This document applies to the threaded ports and column ends of newly designed pneumatic components. Warning: Ports and column ends that comply with ISO 1179 (all parts) or threads that comply with ISO 7-1 cannot be connected to the ports and column ends specified in this document. Note: Ports and column ends with threads that comply with ISO 7-1 are used in ISO 1179-1, but cannot be used in this document, as there are significant differences in thread depth between this document and ISO 1179-1, as shown in Figures 1 and 2.
