#3 Teflon Hose 10'

The #3 Teflon Hose 10' is a professional-grade PTFE racing hose engineered for high-performance automotive fuel and fluid transfer systems. Built for serious enthusiasts and mechanics who demand reliability under extreme pressure and temperature conditions, this braided stainless steel PTFE hose serves as the backbone of fuel injection, boost, and cooling circuits in modified and race vehicles. Whether you're upgrading a fuel system on a turbocharged engine or building a custom cooling loop, this hose meets the precision standards required for modern performance applications.

Constructed with a braided stainless steel outer jacket and PTFE (polytetrafluoroethylene, also known as Teflon) inner core, the #3 Teflon Hose combines chemical inertness with structural durability. PTFE resists fuel permeation, oxidation, and degradation from ethanol-blended fuels—a critical advantage over traditional rubber hoses in high-boost or fuel-injected applications. The 3 AN (3/16-inch nominal ID) size handles mid-range flow requirements typical of fuel rails, boost lines, and auxiliary cooling circuits. Stainless steel braiding provides kink resistance and abrasion protection while maintaining flexibility for routing around tight engine bays. The 10-foot length offers generous slack for custom fabrication without mid-run splicing.

This hose is ideal for builders upgrading stock fuel systems, installing aftermarket fuel rails, or constructing custom boost circuits on turbocharged platforms. Mechanics working on fuel-injected engines benefit from PTFE's superior chemical compatibility with modern pump additives and ethanol fuels. The natural (undyed) finish allows visual inspection for kinks or damage during installation and service. Use -3 AN fittings (JIC 37° or AN/MS flare) at both ends; ensure all connections are properly torqued and use quality hose clamps or crimp fittings to prevent weeping under pressure. Compatible with fuel systems rated up to typical motorsport pressures when paired with appropriate AN fittings and hose clamps.
