- Content
- This SAE Aerospace Standard (AS) specifies scarf-cut polytetrafluoroethylene (PTFE) retainers (backup rings) for use in static glands in accordance with AS5857. They are usually for use in hydraulic and pneumatic systems as anti-extrusion devices in conjunction with O-rings and other seals.
- Content
- This document has been revised to:
-
Add the requirement that no resizing of parts during the manufacturing process is permitted
-
Clarify the use in AS5857 glands
-
Add the stabilized temperature at which measurements shall be taken
-
Delete the dimensional stability test requirement of parts (since this test is performed on each lot of molded material as required by AMS3678)
-
Add the dimensional stability requirement of material tubes to 4.1
-
Include some editorial corrections and improvements
-
Update references
