Vibrant Performance Braided Flex Hoses are available in Stainless Steel and Nylon braided covers which provide excellent abrasion resistance and surrounds a reinforced CPE synthetic rubber inner liner. Our Braided Flex Hoses are suitable for oil, water, fuel, coolant and vacuum service. Also suitable for E85 and methanol use but fumes will permeate through this type of hose when fuel is left stagnant for long periods of time. See our PTFE Flex Hose for extended E85 and methanol use. These hoses are NOT suitable for use as brake lines or other hydraulic pressure lines, nor are they suited for extended submersion in fuel or oil (not recommended for in-tank applications). Operating temperature range: -40 Degrees F to 300 Degrees F (-40 Degrees C to 150 Degrees C).
