So what? I have 60ft of different Brand\sized Tubing for my XETM Project! ROFL :D
But Hey, Small question m8, you actually used the kinda metal O-ring (Which include a black plastic O-ring) right? What is it used for? Protecting the Acrylic from cracking when mounting the barbs on the acrylic side of the block?
I didn't used them on my past loop. Did i do wrong?
