RTV trivia

Super Bleeder!! · 11-09-2006

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.

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.

I've used the red for cat-converter gaskets (still holding great) and for about a month on the turbo outlet (in place of gasket). It also worked great. Seems to hold really well in heat.

I use the blue as toothpaste, it's got a slight grit to it and promotes healthy gums and teeth. Plus as a bonus, it cuts down on late night snacking.

I know I'll be the only one to have a negative post, but it's my true feelings about this stuff. It might be working well for others, however in my younger days on the ole RS-T, I chose to use the copper RTV for a gasket between my 50 trim and a custom flange I made for the 5 bolt hot side (couldn't find a flange to weld onto my DP). I put a heavy bead on the flange and a light smear of it on the turbo for a nice seal. But it didn't. I attempted this over 2 more times, but with no luck. I just ended up purchasing some flange material and cut my own gasket. Endo problems and story.
