18in PTFE Hose -6AN Female Fittings

The 18in PTFE Hose with 6AN Female Fittings is a critical component for high-performance fuel, oil, and coolant systems in modified vehicles. Built for mechanics and enthusiasts who demand reliability under extreme conditions, this braided stainless steel assembly transfers pressurized fluids safely between engine bay components, fuel cells, and aftermarket fuel systems. Whether you're building a turbocharged street machine, a race-prepped engine, or upgrading a fuel injection system, this hose delivers the durability and precision fit required for custom automotive applications.

This 18-inch assembly features a PTFE (polytetrafluoroethylene) core lined interior that resists corrosion, chemical breakdown, and temperature fluctuations inherent in high-boost or naturally aspirated performance builds. The braided stainless steel outer jacket provides superior abrasion resistance and containment in the event of internal hose failure, while aluminum fittings with black anodized finish ensure lightweight construction and corrosion protection. Both ends feature 6AN female straight and 90-degree connectors, allowing flexible routing around tight engine compartments and custom manifold configurations without requiring male-to-female adapter combinations.

Mechanics and engine builders frequently specify this hose for fuel surge tank installations, remote oil cooler setups, and turbo return lines where standard rubber hoses fail under sustained heat and pressure. The 6AN sizing (3/8-inch nominal diameter) handles flow rates common in LS, small-block Chevy, and modern direct-injection platforms without excessive pressure drop. Installation is straightforward for anyone familiar with AN-line assembly; simply connect both female fittings to complementary male adapters on fuel rails, coolers, or distribution blocks. This single-piece, 0.28 lb design eliminates mid-line coupling failures and reduces assembly complexity on custom applications.
