Exhaust flange sealant

[dom14]

Hey Guys,

A sales chick from the Autobarn gave me this sealant, saying it can withstand 1000 celsius degrees.
And it's ideal for the flange surface, to replace the gasket, according to her.

What do you think? Anybody out there who used this product for exhaust flanges successfully(meaning it doesn't turn into dust after few weeks from the exhaust heat)???!!!

G'day Dom,
What temp does the packet say it's rated to?
Worth checking the manufacturers specs first old mate! Cheers

G'day again Dom,
PT appears to only suggest application further down the line mate, IMO I'd be weary of it up the hot end :-) http://www.nissanpatrol.com.au/forums/images/imported/2016/04/161.jpg

Yeah mate, it doesn't exclusively say it's good for the Y pipe flanges.
I read some good reviews on the internet, but who knows.

Cheers Dom,
I'm a little confused why Permatex advertise their rating as (1000?C) on their website?
Is there some '?' heat rating symbol that I very well possibly haven't heard of before ?
I dare say I've just made a goose of myself, but learning is gooda :-)

Of course, I didn't notice it until you pointed it out. :)
Sounds bit dodgy, doesn't it?!!

I reckon "?" stands for the probability, that Permatex themselves don't have much of a clue
of the highest temperature standing of their product. :D
Or their engineers had trouble with their math of converting Fahrenheit to Celsius. :D

For un even surfaces dont you use that Exhaust cement that will expand with heat
and seal any abnormalities

Yes, apparently so.
All these years, I thought Maniseal was more of an exterior cement used for temporarily patching up leaks, cracks, etc on exhaust pipes, manifold, etc.
Apparently, it's more useful between flanges to fill up uneven surfaces, crevices, etc.
Permatex Muffler putty in the OP is probably the same thing as Maniseal with a different brand name.
