Gasket sealer or not

[Command52]

I got all my gasket,Seals, And bearings today for my transmission,pto, and final drives . My question is should i put gaskets on dry , Use a sealer or what would you do . If you recommend using a sealer what type would you use . Im sorry for asking these type questions but i want to do this correct for the long term Thanks Billy

Hi,
I would use a non hardening sealer on the new gaskets. It helps them seal better.

Permatex Aviation Form A Gasket is good, it has an applicator brush in the cap, when I bought one last, anyway. A thin layer of sealer is ok. They sell it at NAPA here in the west US.
If you buy a can of it, stir it well before using it, it settles in the bottom of the can sitting.
Below is a pic of it.

If you would rather use a spray sealer, you can probably find that somewhere.

there are no bad questions, we all ask them except for a few gurus we have here that know ALL , (even if they say they don't. I swear I saw one levitating six inches off the ground in the lotus position when he thought nobody was looking!) ) . not asking would be a far worse mistake.

I like red rtv silicone. Thin layer on both sides works great. In some cases works fine without a gasket even

Form-a-gasket is about the same stuff as Permatex #2:



As long as it's non-hardening and gas/oil resistant, it'll work. Spread a thin coat on both sides of the gasket, especially around the bolt holes.
