Replacing a gasket etc. on my 600sci heat exchanger.
Service manual calls for "Perfect Seal #92-34227-1" on the o-rings.

Is there an equivalent to this at the local parts store?

I just use gasket sealer,,i quess any will do ???? I never had a problem.

Permatex Aviation sealer. Comes with brush in the cap just like perfect seal.

Thanks!

I think the Perfect Seal may be a GM product...at least GM has same sealer in a can labeled GM. I don't think any of the Permatex products are an equal. Perfect Seal is a great sealer for gaskets and the block and intake fittings, etc. Excess also cleans up very easily. IMO, it is worth having a can in your tool box. The shelf life is years...if you tighten the cap

Where do you get the real deal?

Mercury. Sold in a can with a brush. If you want to buy on-line, Bam or Dollar may stock it.

Here is a place to buy Perfect Seal
