Part of Gates' premium Straight Silicone (SS) series, this hose is constructed from high-temperature silicone rubber reinforced with 4-ply polyester fabric for exceptional durability, flexibility, and heat resistance. Rated for continuous operation up to 350°F (177°C) and intermittent spikes to 400°F (204°C), it resists coolant additives, ozone, weathering, and aging. The smooth bore reduces flow restriction, while the thick wall construction prevents collapse under vacuum or high pressure. Ideal for heater core, radiator bypass, or custom coolant routing in performance, classic, or heavy-duty vehicles where stock rubber hoses fail prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features \u0026amp;
