WIP
AMS3020B
This specification covers a petroleum-base reference oil. This fluid has been typically used as a reference oil to estimate the ability of elastomeric compounds to conform to specified requirements after immersion at a specified temperature for a specified time and temperature as required by the material.

Rubber: Fluorocarbon Elastomer (FKM) 70 to 80 Hardness, Low Temperature Sealing Tg -50 °F (-46 °C) For Elastomeric Seals in Aircraft Engine Oil, Fuel and Hydraulics Systems

2019-05-21
WIP
AMS7410
1.1 Form This specification covers high temperature, compression set and fluid resistant fluorocarbon elastomer material to be used in the form of O-rings, compression seals, O-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications. 1.2 Application These products have resistance to a variety of gas turbine engine oils, including high thermal stability (HTS) oils, fuels, and hydraulic fluids, but usage is not limited to such applications. Each application should be considered separately. This fluorocarbon (FKM) has a service temperature range of -65 to +400 °F (-54 to +204 °C) in air. 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, which may be involved in such use.

Rubber, Silicone 1200 Psi (8.27 Mpa), High Modulus 45-55

2019-05-10
WIP
AMS3347D
This specification covers a silicone rubber in the form of sheet, strip, tubing, extrusions and molded shapes. Primarily for parts required to operate or seal from -75 to +205 degrees C (-103 to +401 degrees F), compounded especially for high strength. Silicone elastomer is resistant to deterioration by weathering and by high-aniline-point-petroleum-base oils and remains flexible over the temperature range noted. These products are not normally suitable for use in contact with gasoline or aromatic fuels and low-aniline-point petroleum-base fluids due to excessive swelling.
