Scope
This specification covers a butadiene-acrylonitrile (NBR) rubber in the form of molded rings, compression seals, o-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications.
Rationale
Service Liquid 101 is being replaced by Service Liquid 106 (ARM 200). This revision is intended to update AMS7272 in order to reflect the difference in volume change resulting from the change in test liquids. Acceptance tests have been defined for seal sizes other than those listed in ARP3050. A QPL requirement has been added.

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.
