Silicone. This has maybe the lowest breaking point in terms of stretching, but since an O ring seal never gets pulled or stretched, this doesn't matter. Silicone withstands a huge temperature range. Nitrile is strong, hard to stretch, high tensile strength - but it's not very elastic and it's not good outdoors, and does not have a wide temperature range. Nitrile is no use if you want to have the seals last for ages without being replaced. I'd go for silicone when it comes to O rings.
They are resistant to hydrocarbons, like fuel and lubrication oil. EPDM will swell when exposed to hydrocarbons and is therefore not suitable for most automotive applications, with the exception of window and door seals.
3 years late, but the key difference is that Viton can withstand extreme heat (up to 400° F) and thus is more commonly used with higher performance vehicles as well as some aerospace applications. It also has a much higher resistance to a wide range of different chemicals. However, it performs worse with lower temperatures and has limited flexibility and is much more expensive.
Is it possible to differentiate between them to find out which is which if not having original packaging?
what's used in syringes?
Which seal will be better if it is to used under high pressure and temperature like PCP pumps?

So please explain why Nitrile and Viton used in automotive and what's the difference?

We have a Viton product also

@@ninjareaper3577 Thank you for the most kind explanation of Viton properties
I've been having problems with nitrile hardening up after just six months
What type o ring use in vape tank ?
O.rings
More videos please
Plzz reply me
Try using Fahrenheit & Celsius next time
