SAE - AMS7601
Rubber: Butyl (IIR) Low Compression Set and Low Moisture/Gas Permeability 65 to 75 Type A Hardness for Seals in Desiccated or Other Systems Requiring Resistance to Gas and/or Water Vapor Permeation
|Publication Date:||1 July 2019|
This specification covers a butyl 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 AMS3941 specification.
This butyl elastomer is intended for applications requiring resistance to gas and/or water vapor permeation, but usage is not limited to such applications. This butyl elastomer has a typical service temperature range of -53 to 250 °F (-47 to 121 °C) for static seals. The service temperature range of the material is a general temperature range, but the presence of particular fluids and specific design requirements may modify this range. Each application should be considered separately. It is the responsibility of the user to determine that this specification is appropriate for the environments (temperature range, fluids exposure, etc.) in which it is sought to be used.
