Speedmaster -4 AN PTFE Braided Stainless Steel Hose Line, 20 ft.

The Speedmaster -4 AN PTFE Braided Stainless Steel Hose Line is a 20 ft. length hose designed for high-pressure fluid transfer in automotive, marine, and industrial applications. PTFE (polytetrafluoroethylene) core tubing provides excellent chemical resistance and durability, while the stainless steel braided outer layer adds strength and abrasion protection, making this hose suitable for fuel, coolant, hydraulic, and refrigerant line service.

The -4 AN sizing (1/4" nominal diameter) is a standard fitting specification widely used in performance, racing, and professional fluid system builds. This hose is engineered for reliability in demanding environments where temperature stability and leak-free operation are critical. The combination of PTFE and stainless steel braiding ensures compatibility with a broad range of fluids and prolonged service life, whether you're building a custom cooling loop, fuel system, or high-performance engine bay assembly.
