Teflon Based Gaskets

Rad, the descriptions of the last 2 links I gave say 2 mm and 3mm. I assumed that is the thickness. Am I missing something?

I've mentioned it before, but it bears repeating:

Cotton string and/or cotton rope makes a great gasket. For the tri-clamps with the O-ring channels, you make a cotton o-ring by weaving the ends of the rope together(do a Google search for a how-to), and you then have a permanent and reusable o-ring. For larger or flat surfaces, you can just lay the rope in place and overlap it where the ends meet if you don't want to bother with weaving the ends. For nicely fitting flat surfaces, pure cotton muslin works well, and can be folded-over as many times as necessary to get the thickness you need.

And we can all have machined surfaces. Get some self-adhering fine sandpaper(220 grit and 320 works well, and if you get all anal with it, you can even go up to 2000 grit for a polished surface) and stick it to some thick plate glass, or a marble slab if you have one(marble cutting boards are usually decently flat), then mark the surface with a Sharpie marker, and rub it on the sandpaper in a figure eight pattern, until all the Sharpie is sanded off; you now have a very, very flat surface. If the surface is really bad, begin with a large flat file before going to the paper. With very well fitted surfaces, we need a minimum of gasket, to the point where a sheet of paper might be enough.

Oh, annealed copper wire also makes a dandy gasket if you have solid surfaces and strong, even clamping.

We don't need no damn plastic!

That thicker stuff might be the same as the fancy colored sheeting used in baking... I've tested some of that with high proof and it seems to hold up, but that's not overly scientific testing either... I'm entertaining the idea of possibly making new seals for between my sink strainer and mixing bowl with it, but I haven't pulled the trigger on that yet...

St Pats of Texas sells teflon, silicon and EPDM tri-clamp ferrule gaskets for one to two bucks each. http://stpats.com/index.htm" onclick="window.open(this.href);return false;" rel="nofollow (scroll down)
These have ridge on them though.

Also read today someone mentioned using pasta noodles for a casket. just thought I'ld pass it along... sorry if too off topic...

Would mention that Kentucky Shinner sells them as well on his website (both ring for keg and gasket for ferrule in teflon).
