Marine land 200 gasket?

[Tommy McDonald]

I've been through 3 gaskets 2 wrong size one somewhat correct but it leaks where you take the top off to change the filter media it's a o ring I guess keeps leaking don't see a crack in it. Any idea where to buy a new o ring at without breaking the bank? Marine land website wants a crazy price for shipping and parts.

Have you tried putting some of this on the gasket? I use it on my canister filter gasket. Works.
