Scope
This specification covers a high temperature, compression set and fluid resistant fluorocarbon (FKM) elastomer in the form, of O-rings, compression seals, O-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications.
Rationale
AMS-R-83485 is being superseded by two specifications: AMS7287 replaces AMS-R-83485 (Type I parts) for compression seals and an AMS3000-series specification will replace AMS-R-83485 (Type II parts) for moulded shapes. A new part standard has been produced (AS83485) that will supersede AMS-R-83485/1, although the M83485-XXX numbering system will be retained. The technical requirements of AMS-R-83485 have been maintained in this document, with the addition of a long-term compression set requirement, replacement of STD / SPC class gas turbine lubricants with AMS3085 (i.e. BP Reference Oil 300, representative of HTS class gas turbine lubricants), and the addition of a glass transition (Tg) value/requirement.

Issuing Committee
Welcome to the AMS-CE Elastomers Committee Discussion Forum.
The AMS-CE Elastomers Committee maintains Aerospace Materials Specifications (AMS), Aerospace Recommended Practices (ARP), Aerospace Information Reports (AIR) and Aerospace Standards (AS) on elastomeric materials. AMS-CE, which reports to the Aerospace Materials Division, coordinates and maintains liaison with industry, government and other standardization groups on elastomeric materials. A significant part of this committee is concerned with elastomeric fluid sealing materials, their applications, material development, testing, quality, design parameters and design practices.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
