Sorry cant tell where to get viton but you can easily make them from gasket paper or cardboard...

I've also used Silicone sealer.
ie. Kitchen & Bath Silicone Sealer

Just coat the bung with it & tighten it down.

Thanks for the suggestions----

These bungs are used often so unfortunately sealing with silicon (BD attacks silicon too I think-- maybe you meant urethane?) won't work too well--

Cardboard ??? Hadn't considered that but won't it fall apart rather quickly when continuously wet with BD ?


Tnx,

ReM

If you use a solid cardboard it should hold up fairly well but I have no first hand experience with bung gaskets, they are also very quick to make if your handy with scissors or a sharp knife...
A quality paper gasket will hold up well I am sure. You can buy the material in small quantity's at any auto parts supply house, tractor supply etc...
Good luck,
Jon

Perhaps you could cut them out of a HDPE container such as a washer fluid jug. They are fully compatible with BD. The question is whether it would seal or not.

Check out www.fishersci.com. They sell all kinds of o-rings and science laboratory related items. You'll have to do a little work to figure out the size. Silicones are wonderful, but would be adversely affected by biodiesel, so they're probably not the best thing to use in your intended application.

Viton orings can be purchased at Mercer Gasket & Shim. Webb http://standard-gaskets.com/orings.php
You can order online at very reasonable price.
