My fitting issue was with a pilot on a fireplace insert. I ended up buying a generic replacement assembly for about 1/3 the OEM cost of a single part for my application. My comment is if you need parts, search for a generic to see if it will work….way cheaper and just as good in many instances. Heres my question. Why are breakaway fittings used? Seems like only for pilot applications. And…..are more typical two piece ferule and compression nuts OK to use for these applications on a pilot? Seems to me such fittings would seal without any problems but with gas you need to be sure. The breakaway fittings also seem to be a bit harder to get hold of and more costly compared to 2 piece fittings that seem to do the same thing
