This specification and part standard specifies polytetrafluoroethylene (PTFE) resin material and the dimensional requirements for scarf-cut retainers (backup rings) previously specified 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 seals and O-rings. This document has been revised to: Clarify the use of these parts in glands other than MIL-G-5514 Update the references Add the requirement that no resizing of parts during the manufacturing process is permitted Delete the dimensional stability test requirement (since this test is performed on each lot of molded material as required by AMS3678) Include some editorial improvements
