Product Code:SAE ARP1802
Title:Selection and Application of Polytetrafluoroethylene (Ptfe Or Tfe) Backup Rings for Hydraulic and Pneumatic Fluid Power Applications
Issuing Committee:A-6c2 Seals Committee
Scope: The backup ring is defined. The various types designed for use with O-rings in MIL-G-5514 packing glands, and MS33566 and MS21344 universal fitting installations are described. Guidelines are included for selecting backup rings and backup ring materials, Backup ring installation procedures and precautions are described. The purpose of this report is to provide information that will aid design engineers and maintenance personnel in the selection and use of TFE backup rings (retainers) and backup ring materials for aircraft and aerospace hydraulic and pneumatic fluid power applications.
