Scope
本文件规定了适用于卡套和O形圈密封的24°锥形管接头的通用设计要求、基本尺寸、性能要求以及合格判定试验。此类管接头适用于外径为4 mm～42 mm的金属管。
本文件规定的管接头适用于将金属管或软管接头与符合GB/T 2878.1、ISO 1179-1和ISO 9974-1的油口进行过渡连接(相关软管接头规范见GB/T 9065.2)。
注1： 对于新的应用设计，9.6给出了相关要求。在允许使用弹性密封件的地方，首选符合国家标准并包含弹性密封的管接头设计。
注2： 在规定压力、温度范围之外的条件下使用，参见5.4。
注3： 此类管接头在表1给出的工作压力下工作，实现全流量连接。由于许多因素会影响系统正常运行的压力，这些值不能作为最小保证值,对于每种应用，供需双方需进行充分的试验并对结果进行检查，以确保管接头满足要求的性能水平。
