Thats a perfect application for JB Weld, it will work fine. Rough up the surface for a good bond, make the surface super clean and it will be a permanent repair in my opinion. I've used JB for years in various ways. Each application is different and to varied to list them all. One of the main reasons it may fail is getting it to bond to a given surface, MUST be clean and dry. I've even used it on alloy gas tanks seams that were cracked and previously leaking, works great, WON'T bond if there's even a hint of any liquid leaking into the repair before it sets. Give it a good 24 hours to cure. I like the 'Quick Cure' kind myself, which set's up in about 4 or 5 minutes, but still needs 24 hours to totally cure. In some applications it's better to use the JB that sets up in an hour or so, depends on how much time you need to 'work with it'. For the fitting, I'd use the 'Quick Cure' style, so it won't 'run' or 'drip' before it sets and will only take seconds to apply.
