Flexfab Silicone Hose

Flexfab silicone hose handles the heat, pressure, and vibration that take down ordinary rubber. This collection covers the full Flexfab range of silicone heater and coolant hose, from standard blue heater hose to premium green, 4-ply, wire-reinforced, and high-temp constructions for diesel, marine, transit, and heavy-duty cooling systems. Built in the USA and sold by the foot, box, or reel.
