A 25-foot length of bulk silicone heater hose with a 0.625" (5/8") inside diameter, typically blue in color. Built with polyester ply reinforcement for durability under engine bay heat and pressure, it's used for coolant/heater circuit connections in trucks and heavy equipment where a flexible, heat-resistant hose is needed. It's sold as bulk stock to be cut to length for various coolant hose routing applications, and is cross-referenced to equivalent hose from Gates, Goodyear, and Tectran in the same ID size.
