How to fix crack in CFC not fitting??

[thomasjr16]

I finally got around to using a CFC that I purchased used and it turned out that there's a small crack around the neck of the 1/2" NPT fitting that I thread the TC fitting into.

Should I JB weld this or have a new NPT fitting welded on?

Could try filling the crack with some silver solder, that'd seal it up and be inert. Can't say as it'll add a whole lot in the way of strength.

You could make an attempt to solder it.

I'd JB weld or solder it. I've used JB on my CFC to attach a fitting to great success so far.

I've got the JB weld steel stick or do you think I would have better luck with the epoxy?

Also considering having a stainless welder just weld a 1/2" stainless coupler on or the Triclamp im using and remove the cracked brass fitting altogether. Not sure of the cost for these options yet

I've never used the stick, but the epoxy is stupid simple to use. Mix it up, slap it on, let it cure (they say 24 hours, but I let mine go 72+ to be sure in a cool basement), on you go. File or sand to make it pretty if you must.

Although, it may be best just to replace the fitting if possible (again, using JB!).
