Stainless Steel Braided Flex Hose

Stainless braided hose is the standard for performance fuel, oil and coolant lines because it resists abrasion, holds pressure and looks right on a built engine. This collection covers the Vibrant Performance stainless braided flex hose in rubber core and PTFE lined versions, sold in 5, 10 and 20 foot rolls in common AN sizes.

Rubber core vs. PTFE lined

Rubber core braided hose is flexible, easy to route and works well for oil, coolant and gasoline. PTFE lined hose has a Teflon inner tube that is compatible with nearly every fluid, including E85, methanol and race fuel, and it does not let fuel vapor seep through, so the garage does not smell like gas. PTFE hose needs PTFE-specific hose ends.

Choosing a size

AN sizes describe the line's flow capacity, with -6AN and -8AN the most common for fuel feeds and -10AN to -12AN for oil systems and high horsepower fuel systems. Size the line for the pump and the power level, and match the hose ends to the hose type.

Cutting and assembling

Wrap the cut area with tape and use a fine cut-off wheel or hose cutter for a clean end with no frayed braid. Assemble hose ends with the correct tools and pressure test the line before installing it on the car.

Common questions

Can I use rubber core hose for E85? PTFE lined hose is the safer choice for E85 and methanol, because alcohol fuels can degrade some rubber compounds over time.

Do PTFE hoses need special fittings? Yes. PTFE hose uses an olive or ferrule style hose end designed for the smaller liner. Standard rubber hose ends will not seal on it.

How much hose do I need? Measure each run with a piece of string along the actual route and add a few inches per line for the hose ends and gentle bends.
