Scope
This specification and part standard covers polytetrafluoroethylene (PTFE) resin material and the dimensional requirements for retainers (back-up rings) previously covered by MIL-R-8791 and MIL-R-8791/1. The retainers are intended for use in hydraulic and pneumatic system components as anti-extrusion devices in conjunction with packings and O-rings.
Rationale
This document has been revised to provide some minor technical updates and to include dimensions and tables in metric units

Issuing Committee
A6C2 is responsible for the development of standards, processes, and practices related to Seals, Scrapers and Bearings used in actuation systems for Commercial and Military air vehicles. The panel provides a forum for government engineers, prime contractors, OEMs and suppliers to exchange technical information, regulatory updates, recent technology developments, issues related to system development and in service operation and lessons learned.
Reference
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
