The purpose of this document is to provide the aerospace industry with standardized dimensional criteria for dynamic radial elastomeric O-ring seal glands. It is intended for use in conjunction with ARP 1231, "Gland Design, Elastomeric O-Ring Seals, General Considerations". This document establishes standard gland design criteria and dimensions for dynamic radial O-ring seal applications and provides recommendations for modifying these glands in special applications. There are no provisions in this document for anti- extrusion devices.
