#4 Teflon Hose 20'

The AEROQUIP #4 Teflon Hose 20' (FCC0420) is a high-performance PTFE racing hose engineered for fluid transfer systems that demand extreme reliability under demanding conditions. Constructed with braided stainless steel reinforcement and PTFE core material, this AN4 hose delivers chemical compatibility, temperature stability, and corrosion resistance across a broad range of automotive, marine, and industrial applications. The 20-foot length provides substantial reach for complex plumbing layouts without mid-run connections.

PTFE (polytetrafluoroethylene) core construction resists degradation from aggressive fuels, oils, coolants, and other automotive fluids where traditional rubber hoses fail. The stainless steel braiding provides tensile strength and burst resistance while maintaining flexibility for routing through engine compartments and chassis. AN4 sizing (1/4-inch nominal bore) is the standard for low-to-mid flow applications in fuel systems, cooling lines, and hydraulic circuits. The natural finish allows visual inspection of hose condition and fluid clarity without dye interference.

This hose is built for racing teams, vintage restoration specialists, and technicians who require superior chemical inertness and temperature performance in fuel delivery, coolant circulation, and hydraulic brake systems. It excels in environments where rubber permeability or ethanol fuel compatibility presents a liability. The 20-foot spool length suits complete system builds, allowing single-piece runs that eliminate intermediate couplings and potential leak points.

AEROQUIP is recognized throughout the motorsports and aerospace industries for hose and fluid transfer solutions that meet stringent performance standards. This hose integrates seamlessly with AN4 fittings and adapters across the competitive automotive, aviation, and industrial markets.
