A similar product I have used for some time to re-attach tube caps is muffler cement. Check an auto store for a size and price that fits your needs.

High dollar? At today's rate of inflation, $9.95 for 16 ounces is not what I would call "high dollar" even on fixed retiree income.
Here is a link to the correct stuff.

Since neither of the emaIls had links or pic attached, looked that up on the font of all things Amazoned, there are a few options including JB Weld high temp super glue. The stuff in the caulking gun tube or squeezable tube may just be high temp silicone which I have used but don't think would sustain pulling or twisting of a plate/grid cap. The real issues is that the stuff that looks like it is real furnace cement comes in high dollar plastic tubs, enough to fix a million tubes with.
