18in PTFE Hose -6AN Female Fittings

The 18in PTFE Hose with -6AN Female Fittings from Vibrant Performance is engineered for serious automotive builders who demand reliability in high-pressure fuel, coolant, and fluid transfer applications. Whether you're tuning a modified engine, upgrading a fuel system on a performance vehicle, or fabricating custom cooling loops, this hose assembly delivers the durability and precision fit that separates professional installations from amateur work. The 18-inch length provides flexibility in routing while maintaining structural integrity under demanding conditions.

PTFE (polytetrafluoroethylene) inner tubing resists chemical degradation and maintains stable flow characteristics even at elevated temperatures and pressures common in turbocharged and supercharged systems. The -6AN female fittings provide a secure, industry-standard connection point that eliminates leaks and simplifies integration with aftermarket fuel rails, intercoolers, transmission coolers, and custom plumbing. PTFE's low friction coefficient also reduces pressure drop compared to rubber hose, improving system efficiency and supporting higher fuel flow rates without compromising component longevity.

This hose assembly suits engine swaps, fuel system upgrades, and cooling system modifications where OEM hose routing or material specifications fall short. The compact 18-inch length works well in engine bays with space constraints or as a point-to-point transfer line between major components. Technicians and enthusiasts appreciate the pre-fitted female ends, which eliminate time spent on crimping while ensuring consistent, leak-free connections that pass pressure testing and real-world durability demands.
