In this video I go over the ins and outs of just about every type of fitting one can have in an acrylic or PETG tubing based loop. I explain the function and terminology behind each type of fitting and point out where and why I've decided to put it in my loop.
Below is a list of each type of fitting seen in this guide. A shop link is also provided for each. They are all of the Silver Shining variety.
Make triple sure before you purchase anything that the inner and outer diameter of a given fitting matches up with what size tubing you've chosen to use! Again, the Multi-Link fittings that I have in my build accommodate 10mm/12mm tubing only. All of the G1/4" threaded adapters listed subsequently are of course usable with tubing of any size (or composition) assuming the fittings going into said adapters are also G1/4".
