Silicone has a slightly higher heat tolerance than Viton.
Viton has superior resistance to petroleum products. It's a toss-up between the two. Silicone tends to swell when exposed to oil. This is why you find "sqaure" o-rings on long mileage motors. Viton tends to keep it's shape better under exposure to oil. -Ted
