Built with a braided polyester reinforcement, the tube resists high temperatures, aging, and common automotive fluids — while remaining soft and easy to cut for bespoke routing. It suits cooling systems, heater cores, and other thermal fluid circuits where a dependable, kink-resistant hose is required.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this hose handle engine heat and pressure?\u003c\/h3\u003e\n\u003cp\u003eThe Outus silicone hose is formulated for elevated temperatures and steady pressure.
