Walt good news & bad news. I have one with larger O-Ring & threaded bolt but it has some damage. I ran it with a bit of epoxy on the ridge thats chipped. Never leaked for me but No Guarantee.
Here are 2 pics. Don't think I would feel good shipping it out to have you throw it in the scrap heap. Are you a gambler?? Pay the $10 shipping & you own it. I know it will seal but it's not even close to Mint!
Let me try Pics again??
