I've had a few of these old glass vac brewers and the problem (if it is = one) of the age hardened gasket has concerned me as well. A relatively simple solution to your problem might be to pull off the = gasket or otherwise get it out of the way and then wrap the gasket = seating point of the top piece with soft wrapping cord so that once you = reseat the gasket it will be pushed further open by the cord beneath it. = Should seal both against the pot rim below and the glass/cord/rubber = above. Seems worth a try at any rate. This, at any rate, in more in keeping with the list theme and will = supply my moral and intellectual superiors with a harder target to vent = themselves upon.

I can confirm that "soak in ammonia" doesn't work for Cory and Silex gaskets. What worked for me was "painting" the gasket with food grade silicone caulk.

Rubber oxidezes over time. The great way to preserve it is to treat it with food grade silicon. This is how some divers preserve (my favorite) fins, scubapro jet fins. Interestingly, silicon oxidizes as well, but that usually means discoloration. I could go way into this. Diving is one of my passions that I don't get to do very often. Tight budget and living in the virtual middle of the us means I mostly get to practice. Will On Sun, 9 Jan 2005 12:31pm, Andy Thomas wrote: <Snip> --Will O'Brien--
Well, I tried a technique of prepping the gasket using a soaking and scrubbing in bleach-white, followed by a thorough scrubbing and washing in the kitchen sink, after it dried off, I put it in a plastic bag and am soaking it with armour all. After it soaks for a while, at least a couple of hours or longer, then I'll wash it a couple of times and hope for the best. It was kinda hard, when I realized that it was made in the late 40's, it may benefit from the armour all. Only time will tell. Jim, I did test the vacpot without using any grounds, and it did not have any problems. John, I could hear the sound of air escaping the seal, as it was nice and quiet today in my house. Just slightly, but probably enough with the grounds to create the stall. Setting the Rocky on '20' seemed to work better, but it still stalled about 1/2 way through. So, now, I'll bracket my way back up 2 clicks, see if that helps dial the grind in. Thanks again, for all the help. Gary Andy Thomas wrote: <Snip>

Food Service Direct has replacement seals for about $6. I bought two, one for now, and one in case... Except for scientific documentation and the joy of invention (and I know we like these), there seems little value in trying to fix a 40-50 year old seal when a new one is available...

<Snip> These two sound like they could be fun! Got any more info?
Surely there are rubber o-rings out there that could directly replace an old gasket.

Hi, Have you tried giving them a rejuvenating dip? Get some Blanket Wash from a printer. It is what they use to keep the "blanket" on the offset printing machine clean and in good condition. The gasket can be soaked in it over night even. It will swell up a lot if you do it over night. Give it a few days (in that case) and it will return to good working condition. You will be amased at how well it works. Just the normal dish wash clean to remove any remaining "wash". NOTE it is not the same blanket wash that drycleaners use for bed type blankets. Peter,
Perhaps while you're experimenting you could try one of the $6 replacements from Food Service Direct. Maybe a pot of Uganda Bugisu, perfectly brewed in the Cory. Has anyone tried homemade glass caraffes rather than actually using a purchased vacpot?

While there are certainly a huge variety of old vac pots the majority of them either use a large gasket like the one found at Food Service Direct or a narrow mouth gasket that is available online for a similar price from a company that makes them out of food-grade silicone. Someone posted the info this past summer, but since I don't have a narrow-mouth vac pot, I didn't save the URL. Perhaps the person that posted the info about the narrow-mouth gaskets could re-post the info? Maybe your vac pot is compatible with the narrow gaskets that some old Cory and Silex pots used (and others). Best, Edward
Hi Deward, I was thinking along the same lines as Edward explained... I picked up my last Cory for under $20 online. If the seals indeed are hard to find, perhaps a switched pot might be easier and still economical?

Depending on the contact of the gasket to the glass when sealed, sometimes a wrap with that silicone type tape that isn't sticky but *melds* to itself will work fine and last a long time. BTDT. Also, the local ACE hardware also has a VERY wide selection of plain old corks that can be bored, for the narrow necks, I am thinking. Respectfully, Rich Adams
HomeFOUND glass lab equipment, yes. HomeMADE, no.
Correction.. "rubber type tape", not silicone.
<Snip> <Snip> I can't believe that. Considering everything *else* that goes on regularly here, surely someone is blowing their own glassware! Gene Smith who has blown many things, glass not amongst them

I broke the roasting chamber of my Scirroco long after they were still available. I had one made at the University. They just charged hourly to do it. Cost me a half an hour. The trick is to find stock glass they can easily modify to what you need. Any resident of my state (AZ) can get this done. fjm
I really want to learn to blow and work glass, but never have. On the other hand, I have cast and made my own gaskets, o-rings and such in the past.

Brett: <Snip> replacements from Food Service Direct.
