Gasket for Ziplock screw top containers

. Ziploc screw-top container, verified that it does . if this is the one you were thinking of it didn’t end up working well

cut a circle of a ziploc bag and make a gasket the goes on before the lid?  A doughnut ‘0’ shape would work, but I meant a solid circle, it would prolly be easier to keep up with.

saran-wrap may work, but too thin??

Rich, why don’t you find some Scunci silicone hair ties? The best “rubber bands” ever made, they are 2″ in diameter, and they stretch a lot without breaking (although they do occasionally, but rarely). I just now tried one on a 2-cup Ziploc bowl, and though it’s a wee bit small in circumference, it does work. Carry some spares. I actually have 4-6 attached to each of  my packs, as they have scads of uses. They only weigh 1.3 grams apiece.

Can you tell that I’m a Scunci fan boy?

Good thought.  Foil may work as well.  Should of thought of that.  Something like a mason jar lid seal was what I was thinking of.

You can buy o-ring cord and make an o-ring of any size:

cut to length with a razor blade and glue each end together with super glue.  Slide it into the cap below the threads and it should work fairly well

I ordered some of the O-ring material.  If anyone wants a foot or 2, send me PM  and I’ll send you some.

Hey Rich,

Any update on how this worked?

Sorry, I forgot to look back at this thread until now.  O rings worked OK.  You don’t really have a lot of thread on the container to work with, and when you add the O ring, you only get about a quarter turn of the lid before it gets tight.  That means that the seal isn’t as tight as it could be.  The container won’t leak if you turn it upside down, but it will if you squeeze it.  I’m not sure I’d want to re-hydrate food inside my pack with even the slightest risk of it leaking in bear country.  A flatter materiel would probably work better, or maybe a smaller diameter O ring.

hmmmm…. they sell the same material in sheets.  You could cut out a flat gasket to fit in.  Alternatively, if you only want a thin area of contact, you could just put down a little silicone caulk.
