Reply To: Pressure Tank Replacement Gaskets

[aquasonic]

After rebuilding more of these tanks than I’d like to admit, the more expensive OMC/BRP gaskets are the best quality that I have found. The Sierra gaskets seem to work fine but seem to have a higher “squish factor”. As long as you are tightening the screws, they keep flattening, so the torque needs to be tempered a little.

I’m not sure why this gasket is made from cork sheet, but direct contact with gasoline may have something to do with it.
