I'm using Ice Dragon coolant with Feser Tube Clear/UV Blue
Features
- PVC (Polyvinylchlorid) Material
- UV reactive properties
- Good resistance to oil and grease
- Good dielectric characteristics
- Low flammability
- 5 years uv stable
- Smooth surfaces inside and outside
- TFC – GERMANY Logo applied every 1000 mm
- Highly flexible
So I went with this tubing because it's not vinyl.
It's good to read the labels fine print LOL
