I'm pretty new to brewing, I've only made a couple small batches so far, but I'm loving it and diving all the way in. I've been piecing together all the various equipment I need to start doing 5 gallon batches, and I'm nearly there. Recently I got a good deal on a used Bayou Classic propane burner. I went outside yesterday to fire it up and realized the regulator it came with doesn't have the proper attachment for the standard 20# propane tanks.
So, I went to Lowes today, and physically brought the regulator, but of course the guy I spoke with there didn't know anything about fittings, and couldn't find anything either (it doesn't fit with the standard propane hose fittings). I'm hoping someone on here could point me in the right direction. I've tried doing some research, but have no idea what this fitting is called. Any ideas?
