RTV trivia

[Super Bleeder!!]

I've always wondered why rtv came in such a variety of colors, anyone care to explain it to me as i'm sure the reasoning is more than asthetic.

i.e. what is black for? blue? clear? grey? etc.

The all purpose is going to be black in my opinion.

Go to Permatex's website to know the purposes of the different colors. You will see that permatex black is kind of an all-around solution.

We just got a thing is school about this. The black is the same as the red, They are both high temp but the black is O2 sensor safe. Apparently the red is not. Also they blue and grey have different heat ratings. Id stick to either red or black. And also the different colors have to do with manufactures specs and stuff like that.

Orange I believe is for even higher temps as it has copper in it.

I saw an exhaust manifold with the orange stuff on it. Maybe it would last.

I used the orange as a makeshift exhaust gasket and it worked well.

Search? This has been discussed before.

Black for items in contact with oil, always let the RTV tack up befor install (10-15min read the directions) and I use gray for coolent items.
