Recently I had to start using 1/4" flare couplers rather than my preference of 1/8" FPT - 1/4" flare fittings because the new batch has too large an ID to thread 1/4"-28 for mig tips.
What I've discovered is the 1/4" flare fitting has an unthreaded lag before it hits the hex "nut". A 1"x3/4" T fitting is pretty darned thin where we're drilling and threading it. So thin the brass flare fitting moves when being tapped for the mig tip.
Thanks for posting this, Frosty. I was having a lot of trouble tapping the fittings I picked up locally at Menards. It seemed the ID was slightly too large to get a good tap (the MIG tip would move slightly when screwed in.
I ended up buying some from an online supplier. Here's a link: Supply House.com. The brand is Jones Stevens and they tapped much better than the ones I picked up at Menards. Just sharing for the other newbies that are starting out like I am.
