Chuck shared this hack with us and it is awesome so I wanted to share it with you! These are 12AN parallel hose clamps designed to dress up hoses and braided lines on custom engines. They are designed to hold .94 inches inside, and 3/4" EMT Conduit is .92" OD. Chuck said he used them and they worked perfectly! As a bonus, it looks like the bolt is the same size as the Maker Pipe hardware.

I will link some down below, but you can get them locally at most auto parts stores and other places. Just look for the 12AN and you should be good.
