Araldite or other expoxy-glues are generally good (though they probably won't claim to be food-grade). For a still I think thermal-cycling may cause the seal to fail, see if you can find some rubber or cork? I assume it's a pressure-cooker? L

its 4 a still but torubber or cork wont help me for this application. its a joint above the cooker i want to seal .

Try Araldite then, but cork & a lot of rubbers will take high temp. I'll look forward to seeing it finished! L

in the end i have used oven sealant the stuff used to make seal on oven doors. wash was cornflakes and molasses, got a good pint on first run. tastes great .

(Sounds like he might have a better design, that cork wasn't the tightest of seals) L

I guess it would not be polite to tell somebody to put a cork in it.
