(R) Elastomer: Acrylonitrile Butadiene Rubber (NBR) Hot Oil and Coolant Resistant, Low Swell 45 to 55 Type ‘A’ Durometer Hardness for Products in Engine Oil Systems/Coolant Systems
|Publication Date:||1 May 2020|
This specification covers an Acrylonitrile Butadiene Rubber (NBR) 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 AMS7000 series specification.
This material type has resistance to hot petroleum based lubricating oils as well as glycol-type coolants, but usage is not limited to such applications. This material type has a typical service temperature range of -40 to +212 °F (-40 to +100 °C). 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.
Order of Precedence
