This SAE Aerospace Standard (AS) provides dimensions and procedures for a standardized test fixture used to evaluate the static performance of O-rings and other seal types in glands per AS4716 and AS5857.
This specification covers a chloroprene (CR) rubber that can be used to manufacture product in the form of sheet, strip, tubing, extrusions, and molded shapes such as window channels, bumper pads, chafing strips, etc. For molded rings, compression seals, molded O-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications, use the equivalent AMS7XXX specification.
This specification covers requirements for the material, design, testing and packaging of straight thread tube fitting boss O-rings. O-rings covered by this specification are acrylonitrile-butadiene rubber.
