Rubber: Butadiene-Acrylonitrile (NBR) For Elastomeric Seals in Aircraft Synthetic Hydrocarbon Based Hydraulics Systems

2007-08-16
WIP
CE07AA
Form: This specification covers hydraulic fluid resistant Butadiene-Acrylonitrile (NBR) rubber used to produce seals, gaskets and other molded products. 1.2 Application: This material is used typically for contact with synthetic hydraulic fluids conforming to MIL-PRF-83282, MIL-PRF-46170 and MIL-PRF-87257, but usage is not limited to such applications. Each application should be considered separately. This material has a service temperature range of -65 to +275F (-54 to +135C). 1.3 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 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.

AMS7255A
This specification covers a tetrafluoroethylene/propylene rubber (FEPM) in the form of molded rings. These rings have been used typically as static sealing rings for continuous use from -5 to +232 degrees C (+23 to +450 degrees F) in dry air, hydraulic fluids, synthetic lubricants, and high pH chemical decontamination fluids, but usage is not limited to such applications.

HISTORICAL
AMS7257B
This specification covers a perfluorocarbon (FFKM) rubber in the form of molded o-rings. These sealing rings have been used typically in applications in contact with air or a variety of fuels, lubricants and hydraulic fluids from -15 to +290 degrees C (+5 to 554 degrees F), but usage is not limited to such applications. Each application, however, has to be considered individually. Instances are known when these rings have been used below -15 degrees C (+5 degrees F) and above 290 degrees C (554 degrees F). The cross section of such rings is usually not over 0.275 inch (6.98 mm) in diameter or thickness.
