Rubber: Fluorocarbon Elastomer (FKM) Low Temperature Sealing Tg -40 °F (-40 °C) 70 to 80 Type ‘A’ Hardness For Elastomeric Seals in Aircraft Engine Oil, Fuel and Hydraulics Systems
橡胶:氟碳弹性体(FKM)低温密封Tg-40°F(-40°C)70至80“A”型硬度 用于飞机发动机机油、燃料和液压系统中的弹性密封
This specification covers a fluorocarbon (FKM) rubber in the form of O-rings, compression seals, O-ring cord, and molded-in-place gaskets for aeronautical and aerospace applications. For sheet, strip, tubing, extrusions, and molded shapes use the AMS3353 specification which is intended for that use.
