I am getting ready to purchase components for a new loop, it's my first one and I would like to use rigid tubing but I and wondering about larger than 3/8 Id and 1/2 OD tubing and fittings. I noticed that EK sells 12mm ID x 16mm OD tubing and fittings. Has anyone here used these sizes and do and compression fitting work or do you have to use special fittings designed for rigid tubing? My reasoning is that I think the smaller tubing looks kinda slim and I am wanting a beefier look.
