18in PTFE Hose -8AN Female Fittings

The 18in PTFE Hose with -8AN Female Fittings is a professional-grade fuel, oil, and coolant line assembly designed for high-performance automotive systems and custom engine builds. Built for mechanics and enthusiasts who demand reliability under pressure, this hose assembly connects dual -8AN female ports with precision, eliminating leaks and vibration in demanding fuel injection systems, turbo setups, and modified cooling loops. The 18-inch length provides flexibility in tight engine bays while maintaining a compact footprint ideal for custom fabrication work.

This assembly features a PTFE (polytetrafluoroethylene) core lined inside a braided stainless steel outer jacket, creating a dual-layer barrier that resists heat, abrasion, and chemical degradation from modern fuel blends and synthetic oils. The straight female and 45-degree female -8AN fittings are machined from anodized aluminum, offering weight savings critical in performance applications while maintaining structural integrity at high pressures. PTFE lining prevents swelling and maintains consistent flow rates, essential when tuning fuel pressure regulators or integrating auxiliary cooling systems where precise delivery matters.

Mechanics working on turbocharged engines, fuel system upgrades, and custom water cooling setups will find this hose assembly indispensable for routes requiring both straight and angled connections. The -8AN standard matches common fuel rail systems, return lines, and auxiliary fluid circuits on late-model performance vehicles and complete custom builds. Installation is straightforward with standard -8AN thread tools; the black anodized finish resists corrosion under the hood while maintaining a professional appearance in visible engine bays.
