Subject: Sunbeam C50 vacuum pot question
I just bought one of these on eBay but the rubber O-ring seal,
although still soft, is possibly worn. It does not make a tight seal
between the upper and lower pots. I was hoping this would be a good
reserve vacuum pot since I use a Sunbeam C30C every day and love the
great coffee it makes from my home-roasted beans. I have zero
experience with the C50, and it seems to me that the pots should stick
together with some force when the two levers are actuated. They
don't! They are very easily separated. With my C30C I keep my
fingers crossed every day that the rubber gasket will not split when I
remove the upper pot since the seal it makes is very tight. I have
not tried making coffee in the C50 yet because the seal seems
inadequate to prevent vacuum loss.
Does anyone know if replacement O-rings for the C50 are available
anywhere? Any help appreciated.

What I've used on vac pot rubber gaskets as long as they're not rock hard is
a product something like this one http://www.autogeek.net/pinvinrubpro.html
that's Urethane enriched with polymers that keep rubber soft & supple. I'm
in Canada & the product I use is from Canadian Tire & was discontinued, but
I have enough to last me.
I have a pristine C50 but haven't looked at it in a couple of years, but I
believe that if it's a bit loose of a fit., the locking arms hold the top
down tight enough that it's not a worry.
Craig.

The O-ring gasket is not hard. It is very soft and pliable and would
probably make a good seal if it were a bit thicker. It just isn't a
tight fit when the pots are together and the pots are very easily
pulled apart. I'm afraid it won't be a good enough seal. I need a
new O-ring with just a little bit larger cross-sectional diameter.
I've measured this one with a micrometer and it is 0.335 inches in
cross-sectional diameter. I reckon it should be 0.375 inches or 3/8".
Unlike the unique seal on the C30 series of pots the C50 uses just a
simple O-ring of this specific size, and some supplier must have them
available since O-rings are used as seals in all manner of things.
It's just a matter of finding that supplier. I guess I'll resort to
Google to try to find one. If I can't find one then I'll try to put a
layer of rubber between the top pot groove and the inside diameter of
the O-ring to expand its diameter a little. A strip of motorcycle
tire inner tube or something similar like surgical rubber that I can
cut a 1/2" wide cross section out of and stretch it over the top pot
groove before putting the O-ring on should do the trick. Anyway, I've
just won another auction for a C50 top pot with seal, so I'll see how
that fits.

Howdy Craig!
Is this certified food safe?

No, of course not! I would apply it & let it work on stuck gaskets, & I've
gotten everyone off with no cracking or splitting. I would then run the
gaskets under 140F tap water thereabouts to remove the slipperyness. The
gaskgets never contacted coffee & I've never had a problem. Just like the CG
thread about the Permetex sealants for the air roaster/fluidized glass
chamber to base & the hoopla about all that..
For the paranoid, I'd suggest glycerin or a food grade grease applied then
wiped off.
