(R) Elastomer: Fluorocarbon (FKM) Rubber High-Temperature-Fluid Resistant Low Compression Set 85 to 95
|Publication Date:||1 October 2017|
This specification covers a fluorocarbon (FKM) elastomer that can be used to manufacture product in the form of sheet, strip, tubing, extrusions, and molded shapes. For molded rings, compression seals, O-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications, use the AMS7259 specification.
This Material Type has been used typically in components in contact with air and a wide variety of fuels, synthetic lubricants, and specific hydraulic fluids from -20 to +400 °F (-29 to +204 °C), but usage is not limited to such applications. 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.
This class of fluoroelastomers is not recommended for use in high temperature stabilized, "HTS", engine oils. Each "HTS" oil should be evaluated separately.
Order of Precedence
This specification is in addition to and in no way limiting, superseding, or abrogating any contractual obligation as required by the applicable procurement document. In the event of conflict in requirements, the order of precedence shall be:
Procurement Document or Contractual Agreement and all statutory and regulatory requirements (excluding this document)
Applicable purchaser's drawing and/or design data
Specifications referenced on the drawing
All specifications referenced in this document
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.
