Tig weld vs J-B Weld...LOL

Im with 69. Just fit the fitting in, drill a few small through holes and tap some solid pins in. Apply favorite sealer and you'll be set. wanna remove the fitting? Tap the pins out and pull it off. Thats some sunday night engineering but I don't have a TIG welder (yet) either. 16psi is nothing for a few steel pins.
