Aviation Aerospace Fluorine Rubber Fuel Hose The Material of this rubber fuel hose contains 4 layers: Inner FKM layer, Anti permeability, high and low temperature resistance (-40 ℃~135 ℃/150 ℃), aging resistance, high oil resistance etc., mainly used in high-end fields such as automobiles, rail transit, aviation, aerospace, etc. Intermediate ECO layer, Heat resistance, cold resistance, oil resistance, ozone resistance and other properties, better connected into one entity. Reinforcement aramid or polyester layer, h.igh strength, high temperature resistance, corrosion resistance, light weight, 5-6 times the strength of steel wire. Outer ECO layer, Non hardening at temperature -40 ℃~135 ℃/150 ℃, resistant to corrosion, ozone, aging, high and low temperature. no cracking, more safe. The features are four layer protection, Impermeable, good resilience, adopt special formula that combines imported FKM, ECO, and aramid wire, excellent resistance to high and low temperat…
