#4 Teflon Hose 10'

The #4 Teflon Hose 10' from AEROQUIP is a professional-grade PTFE racing hose engineered for high-performance fluid transfer in motorsports, aerospace, and industrial applications where reliability under extreme conditions is non-negotiable. This 10-foot hose assembly serves drivers, mechanics, and technicians who demand superior performance from their fuel, oil, and coolant systems. Built to withstand the thermal and pressure demands of competition engines and precision machinery, this hose eliminates the inconsistencies of rubber alternatives and delivers predictable, long-term durability.

The #4 Teflon Hose features a braided stainless steel reinforcement jacket surrounding a PTFE (polytetrafluoroethylene) inner core, a combination that resists chemical degradation, extreme temperatures, and pressure spikes that would compromise rubber hoses. The stainless steel braid provides mechanical strength and abrasion resistance, while the PTFE inner tube eliminates permeation—the slow seepage that degrades performance in sealed systems. Rated for 4 AN (aerospace nominal) sizing, this hose accommodates standard -4 AN fittings and delivers consistent flow characteristics across a wide temperature range, making it ideal for fuel injection systems, turbo feed lines, and transmission cooler circuits where thermal stability matters.

Users including race teams, custom fabricators, and performance shops choose AEROQUIP PTFE hose for critical applications where standard rubber cannot perform. The natural (undyed) stainless braid finish integrates cleanly into engine bays and custom builds. Installation is straightforward with standard -4 AN compression or flare fittings; ensure proper routing away from heat sources and sharp edges to maximize service life. At 10 feet, this length accommodates mid-size engine installations, fuel cell conversions, and auxiliary system runs without excessive slack or joins.
