This specification covers an acrylonitrile-butadiene (NBR) rubber in the form of molded rings, compression seals, O-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications. For sheet, strip, tubing, extrusions, and molded shapes, use the AMS3XXX specification which is intended for that use.
AMS7274K results from a Five-Year Review and update of this specification.

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.
