About This Item

 

Full Description

This specification and part standard covers polytetrafluoroethylene (PTFE) resin material and the dimensional requirements for retainers (back-up rings) previously covered by SAE AS 8791 and SAE AS 8791/1 which superseded MIL-R-8791 and MIL-R-8791/1.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 conjunctionwith packings and O-rings.
