12in PTFE Hose -6AN Female Fittings

The 12in PTFE Hose with -6AN Female Fittings from Vibrant Performance is engineered for serious fuel system, coolant, and fluid transfer applications where reliability and longevity matter. This hose assembly is purpose-built for custom engine builds, turbo conversions, and high-performance fuel rail setups where standard rubber hoses fall short. Whether you're upgrading a modified fuel system, installing a secondary coolant loop, or routing brake fluid in a race car, this premium hose delivers the durability and precision fit that separates professional-grade work from amateur installations.

PTFE (polytetrafluoroethylene) construction provides superior chemical resistance, thermal stability, and flexibility compared to traditional rubber or braided nylon hoses. The -6AN female fitting designation indicates a 3/8-inch inner diameter with AN-standard threads, compatible with industry-standard -6AN male connectors found on fuel pressure regulators, filters, injector rails, and distribution blocks. At 12 inches in length, this hose size accommodates engine bay routing without excessive slack, while the reinforced PTFE core resists degradation from ethanol fuels, high-temperature coolants, and aggressive brake fluid formulations that can compromise rubber seals over time. The female-to-female configuration allows flexible plumbing pathways in custom fuel systems and cooling circuits where space or component layout demands unconventional routing.

This hose assembly is ideal for mechanics, engine builders, and motorsports enthusiasts fabricating custom fuel delivery systems, turbocharger intercooler plumbing, or secondary cooling circuits on forced-induction platforms. Install it between fuel pumps and regulators, across firewall bulkheads, or within tight engine bay manifold clusters where standard rubber hoses degrade from radiant heat or abrasion. The Vibrant Performance construction ensures compliance with fuel system pressure requirements and thermal cycling found in street performance, autocross, and drag racing environments. Verify -6AN fitting compatibility with your fuel block, regulator, and pump outlet before ordering to ensure seamless integration into your existing hydraulic layout.
