Why Choose Silicone?
There are several advantages to silicone hoses beyond just their cosmetic aspect. Primarily the higher resilience to high underhood heat (such as in a turbocharged application, or even just the additional heat fromĀ longĀ tubeĀ headers). They do not harden up or dry rot from excessive heat, these have an operational heat range of -40 to 475 degrees. These hoses will maintain their pliability and flexibility throughout their entire lifespan. Furthermore, the multi-ply silicone can handle much higher pressures than traditional rubber, these hoses are burst tested to 250psi and can sustain operational pressures up to 72.5psi (about 4.5 times the standard cooling system pressure). Silicone is much more impervious to oil based contaminants, and will not break down like rubber when exposed to oil or otherĀ lubricants. When compared to rubber hoses, the service life of silicone is unparalleled, these would likely be the last set of hoses you would ever need to purchase for your truck.
