Newbie Question of the Week

Where can I get rubber to cut my own heat exchanger gaskets?
Is there a specific type/thickness of rubber that needs to be used, or will any rubber mat do?

Or am I being cheap, and should I just pay the $3.00/each for a few Westerbeke gaskets?

go to and type in gasket material. You can choose from hundreds of different materials and sizes, some sheet, some rope, o-ring, etc. and you'll no doubt find what you need.

the perfect dive boat is one you're on...

McMaster, Grainger, or any real auto parts or machine shop supply. You're probably looking for neoprene or teflon sheet, not just "rubber". And if you really want to get slick...check out where you can download CAD software, lay out your gaskets, and have them cut and mailed back to you all in one shot. (Although, I suspect it will cost more than $3 each.)

If the ready made gaskets are only $3 I would go with that. Doubt you could save much if anything trying to make your own. Plus how much time would you spend and would they fit and seal as well after you were done?
The water is always bluer on the other side of the ocean.
