>>know years ago most supply houses didn't like to deal<<

I still lmao over that....we have a supply house down the street from me and I am getting some of the supplies there. But years ago they'd ask if I was licensed and then tell me to hit the road. Once Lowes/HD moved in...they ran ad's...public welcomed!!! He did say to me...thank god...that they still wont sell gas fittings to those not licensed.

Yes I've only checked the places you mentioned...but odd they carry other reducer sizes but not that one. I'll give the supply house a call this week.

Thanks!
