Scope
This document specifies the dimensions and performance requirements of metric external hexagonal and internal hexagonal plugs used in oil ports that comply with ISO 99741. The plugs applicable to this document can withstand a maximum working pressure of 63 MPa (the maximum working pressure is determined based on the plug's end dimensions, material, structure, working conditions, and application scenarios, etc.). Plugs that only meet the dimensions specified in this document cannot guarantee their rated performance.
