This SAE Aerospace Standard (AS) covers solid polytetrafluoroethylene (PTFE) retainers (back-up rings) for use in static glands in accordance with AS5857. They are for use in hydraulic and pneumatic system components as anti-extrusion devices in conjunction with O-rings, packings and other elastomeric seals. Because of the construction of groove dimensions, back-ups specific to rod applications are designated “R” - Rod (Female), back-ups specific to piston applications are designated “P” - Piston (Male). Retainers specified herein have been designed for a temperature range of -65 to 275 °F (-54 to 135 °C) and a nominal operating pressure of 3000 psi (20.6 MPa) for code 09 material and 5000 psi (34.3 MPa) for code 10 material. Material codes are based on AMS 3678 material types.

NOTE: This specification includes material tests but does not include hydraulic or pneumatic performance tests.
This SAE Aerospace Recommended Practice (ARP) provides guidelines for the application of polymeric bearings for linear actuation systems. Design considerations are included for recommended fit and function in conjunction with material selection and load-bearing capability.
This SAE Aerospace Information Report (AIR) contains data relative to the chemical nature of aerospace fluids and relates each to its empirical effect upon elastomeric components. Since the compatibilities of elastomers are determined by the compounding as well as the nature of the base polymer, the elastomers considered are limited to finished compounds for which material or performance specifications can be referenced.
THIS STANDARD ESTABLISHES THE DIMENSIONAL AND VISUAL QUALITY REQUIREMENTS, LOT REQUIREMENTS, AND PACKAGING AND LABELLING REQUIREMENTS FOR METALLIC-ENCASED COPPER GASKETS MANUFACTURED PER AMS-HH-G-101 TYPE III - STYLE J. IT SHALL BE USED FOR PROCUREMENT PURPOSES.

THIS STANDARD ESTABLISHES THE DIMENSIONAL AND VISUAL QUALITY REQUIREMENTS, LOT REQUIREMENTS AND PACKAGING AND LABELING REQUIREMENTS FOR O-RINGS MOLDED FROM AMS-R-7362 NITRILE RUBBER. IT SHALL BE USED FOR PROCUREMENT PURPOSES.
This recommended practice provides the design criteria for static elastomeric O-ring seal applications, axial compression (face type) groove dimensions for aerospace metric O-ring sizes specified in MA2010. The conditions considered to formulate the design criteria are also described, e.g., seal squeeze and groove volume to accommodate O-ring swell.
