Placed my initial order last night, will likely have to place a second one to pick up some miscellaneous pieces once my brew stand arrives from PinupBrewery, but wanted to start getting my tubing ready.

My plan is to use street elbows with the male threads removed and stretching the tubing over the end; does anyone have a good idea of what Oeitker pinch clamps would work well with this? I'm thinking about ordering 25 from Mcmaster.com (part #52545K73) which has a clamp range of 45/64" (.703") to 53/64" (.828"). I know others have stated that the clamps aren't necessary when doing this, but I'd like a little extra piece of mind and try to use the Oeitker-style ones whenever possible.

I wrapped the male end of the elbows with about 6-8 wraps of teflon tape before stretching the tubing over it. I'm sure the threads ate up the tubing a little bit, but when I took one off I didn't notice anything other than an indention. It's not ideal but it's worked so far for 2 brew sessions without any issues.

That is a good idea. What I whouldve done if I didn't have great friend thats a welder that does all that stuff for me.

Has anybody tried using a threaded on one end 1/2 npt stainless 1" length pipe instead of grinding threads on the street elbow?

McMaster-Carr Has these for $1.87 Part Number: 9157K13

The OD of the unthreaded part will be slightly larger than the threads so you will have to stretch the silicone tubing some more.

Looks good. Just placed an order for all my valves, fittings and tubes. Hope I got everything right.

Why not use a D style fitting, screw the male end of the elbow into it, then thread a 1/2" NPT x 1/2" barb into the female end?

Am I missing something here?

My guess is that the reason no one has pursued that route is cost. Those 1/2" barbs are not cheap, even from reasonably priced distributors.

The size of the 1/2 hose barb is significantly smaller than 1/2".

Check out Bobby_M's video about the quick disconnects and hose barbs:
