Polyurethane Vs. Silicone tubing

[aumoenoav]

Any experience with using Polyurethane https://www.ebay.com/itm/METRIC-IMP...hash=item3ae86fd52b:m:msofSe-3ovhKlcfSr9T7XLQ or Silicone (https://www.ebay.com/itm/Silicone-V...hash=item4b150cab09:m:mre33xraw8YHTLLyONxS5Yg) tubing for dosing pumps?

I have used them with out any issues
You can pick up polyurethane line 1/4 at Home Depot. Just bought so more line as I am moving my dosers out from under my stand to my garage. Easier for my to keep and eye on things and I am getting to old to crawl around on the floor under a tank. [emoji3]
