I found a few around the house that can handle up to 20inHg. Kirkland's instant coffee for the 3.6L, soap pod container (like Tide) can handle up to 22inHg. A large mayonnaise plastic jar can handle up to 18inHg. The kimchi container can go as high as 22inHg. All these larger ones are 5L size. My "free" containers
But man, 36inHg. That is one tough wall container. Try to keep the new accessories total to less than $50 if you can. I try a budget of $30. So far, so good.
