Of course I tried this first. Depending on the valve, it kinda worked but I lost a lot of air from the threads.
My 3 year old has guaranteed that I can never quite find what I need. No roll of teflon tape but a little sliver on a hose fitting I'm not using now. I used that and it improved the seal. On one wheel, it was perfect and on the other, it was okay. The air loss is coming from around the valve now, not the threads in the head.
Unfortunately, I have to change how far it's screwed for each valve or I'd silicone it in.
My idea is to have a more functional pump on my way out in the boonies bike, which this fits perfectly in.
