Scope:

This specification and part standard covers polytetrafluoroethylene (PTFE) resin material and the dimensional requirements for scarf-cut 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 seals and O-rings.

Rationale:

As a result of the 5 year review, this document has been revised to update the references and the prohibition of use of these parts in glands other than MIL-G-5514 has been further clarified.
