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 from long tube 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 other 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.
