Nope, don't like rigid tubing as it's too unforgiving to work with. Past experience with acrylic is that it crazes over time so I never have any in my loop hence the plain acetal blocks. PETG isn't compatible with my coolant either, as I use ethelyne glycol.
The plan down the line is to move to coloured 1/2" ID silicone hose.
