SAE AMS7338 2013 Edition, February 1, 2013
Rubber: Butyl (IIR Abbreviation) Phosphate Ester Resistant 65 to 75
Hardness For Seals In Hydraulic Systems, etc.
Description / Abstract:
Form
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. As AMS3238 is no longer valid for O-rings. For O-rings, the requirements of AMS7338 shall be met wherever AMS3238 is specified.
Application
These products have resistance to phosphate ester fluids and/or low permeability to gases, but usage is not limited to such applications. Not suitable for use in contact with petroleum-base fluids due to excessive swell. Each application should be considered separately. This Material Type has a typical service temperature range of -75 to +250 °F (-59 to +121 °C) in air.
Safety Hazardous Materials
While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
