Vibrant PTFE Flex Hose Assembly -8AN 24in Length Hose End Style Straight/Straight

Factory-Crimped PTFE Flex Hose Assembly for Fuel, Oil, Coolant, and Nitrous Lines

The Vibrant 29012 is a pre-assembled PTFE-lined flex hose featuring a 24-inch length, -8AN hose ends, and a straight-to-straight end configuration with black anodized aluminum crimp fittings. PTFE (polytetrafluoroethylene) lining makes the 29012 compatible with a wide range of fluids including gasoline, ethanol-blended fuels, diesel, engine oil, transmission fluid, coolant, and nitrous oxide. Unlike braided stainless lines with push-on or reusable screw-together fittings, this assembly uses hydraulically crimped aluminum end fittings that are installed at the factory under measured pressure, eliminating any fitting thread gaps and producing a leak-free, pressure-tested connection at both ends. The nylon braided outer sheath provides protection against abrasion and UV degradation. The 29012 is a universal hose assembly that can be used wherever a -8AN 24-inch straight-to-straight line is needed. It is not rated for high-pressure hydraulic brake or power steering applications; it is intended for fuel, oil, coolant, and similar low-to-medium pressure circuits.

Key Features

• PTFE-lined inner core compatible with gasoline, ethanol fuels (E85), diesel, engine oil, coolant, nitrous oxide, and other automotive fluids
• Hydraulically crimped factory fittings installed with a calibrated crimping tool; each assembly is pressure-tested to its rated working pressure before shipment
• Black anodized aluminum crimp-on hose end fittings resist corrosion and provide a clean, polished appearance
• Nylon braided outer sheath offers abrasion resistance and UV protection for exposed routing applications
• Straight/straight hose end configuration; -8AN size on both ends
• 24-inch overall length; ideal for engine bay fuel, oil, or coolant lines and remote cooler plumbing
• Not for use in high-pressure hydraulic applications (brake lines, power steering)
• Prop 65 compliant

Frequently Asked Questions

Yes. The PTFE inner liner in the 29012 is fully compatible with E85, methanol blends, and other high-ethanol fuels that degrade standard rubber-lined hose. PTFE is chemically inert against a broad range of fuels and solvents, making this assembly a common choice for high-performance and flex-fuel builds where ethanol compatibility is required throughout the fuel system.

The -8AN designation corresponds to a nominal 1/2-inch or approximately 0.44-inch inner diameter. The PTFE liner maintains this ID consistently across the length of the assembly. For flow rate calculations, use 0.44 inches as the working ID. The -8AN crimp fittings at each end are compatible with standard -8AN AN fittings and adapters from any manufacturer.

No. Hydraulically crimped fittings are a single-use attachment; the crimping process permanently deforms the fitting sleeve around the hose end. If the hose ever needs replacement, the entire assembly must be replaced. The advantage of crimped fittings over reusable screw-together types is that the factory-calibrated crimp provides a leak-free seal that has been pressure-tested, whereas reusable fittings depend on proper field installation torque for sealing.

Yes. PTFE-lined hose is a common choice for turbocharger oil feed and drain lines because PTFE resists the high heat generated at the turbo center section. For oil feed lines, -8AN is a common size for many turbo applications. Confirm the required AN size and length for your specific turbocharger oil feed or drain fitting before ordering, as -8AN may not be the correct size for all turbo configurations.

Yes. The -8AN fittings on the 29012 use the standard AN thread specification (3/4-16 UNF) and are compatible with any -8AN male or female adapter, bulkhead, or hose end fitting from any brand. No special adapters are required for standard AN plumbing.

Yes. The Vibrant PTFE pre-assembled hose line is rated for nitrous oxide service. PTFE is one of the few liner materials compatible with NOx systems; standard rubber or nitrile-lined hose is not suitable for nitrous applications. Always verify that all other fittings and plumbing components in a nitrous system are similarly rated before pressurizing the system.

The pre-assembled PTFE crimp assemblies like the 29012 arrive ready to install with no additional fitting purchase required. The factory crimp is highly consistent and pressure-tested. Stainless braided hose with reusable fittings allows custom length cutting and fitting selection in the field, which suits custom fabrication or complex routing. The crimp assembly is the better choice when you know your exact length and end configuration and want a no-assembly-required solution.

Vibrant Performance provides a manufacturer warranty on their hose assemblies covering defects in materials and workmanship. Under the Magnuson-Moss Warranty Act, using an aftermarket hose assembly in a non-OEM application does not void the manufacturer warranty on unrelated vehicle systems.
