Polyurethane Tubing Reef safe?

[Lemons]

Hey all! I was trying to find some vynl or polyethylene 7/64 ID tubing for my Kamoer X1 pump... but the only stuff i could find that would fit is a micro fuel line... and its Polyurethane. I tried looking up some kind of SDS for this material and all I get is "micro fuel line is manufactured with polyurethane, with no plasticizers that can cause flow contamination or tube hardening."

so i was wondering if anyone has any experience with this material.

P.S gonna use it to dose some Kalk

Good question. I've always used the tubing supplied with my dosers.

Normally i would too, however I cant find the oddly sized tube in my mess of airlines lol so maybe I’ll just crimp down a regular airline… but not very comfortable considering the ID difference is kinda large
