本文介绍的凹槽设计适用于机械加工或成型的金属密封件，其配置类似于图3所示，在内部压力或真空条件下运行，且经买方或制造商特别鉴定或推荐用于该空气。它们也适用于金属o形密封圈（如MS9142、MS202至MS9205），需要与机加工或成型金属密封件互换。对于不要求互换性的金属o形圈槽设计，请参考ARP 674。

Groove designs presented herein are applicable for use with machined or formed metal seals which are similar in configuration to those shown infigure 3, which operate under internal pressure or in vacuum service and which have been specifically qualified or recommended by the purchaser or the manufacturer for use with this AIR. They are also applicable for use with metal o-rings (e.g., MS9142, MS202 thru MS9205) where interchangeability with machined or formed metal seals is desired. For metal o-ring groove designs where inter-changeability is not a requirement refer to ARP 674.
