MATERIALS: Simrit, the industrial products division of Freudenberg-NOK, recently expanded its material product line with the debut of the F273 material for the aerospace industry. The new material conforms to all requirements of AMS-7273. F273 fluorosilicone rubber products are manufactured at Simrit’s International Seal® facility located in Santa Ana, CA.
The F273 material is used in high-performance, high-pressure jet fuel systems and is resistant to jet fuels and synthetic turbine lubricants with a typical application temperature range from -70 to 200C. The AMS-7273 specification is difficult to meet because of stringent requirements for aged properties - meaning that no appreciable property changes are allowed at exposure temperatures up to 200C in dry heat. Additionally, this specification is difficult to meet with the high-pressure, extreme temperature simulated component testing in fuel.
