Dosing pump tubing

[Viperdragon]

I was wondering is anyone knew the size of the tubing in a jebao doing pump head. I'm running kalk through one of the heads and it is only lasting about 3 months before it splits.

I had to look it up
Amazon product ASIN B08MF5XHR5
ID 3mm X OD 5mm

I remembered 3 or 5 (?) and now I think I know why.

i also remember searching through the varios materials used for dosing pumps and from what you have described your's has the right size but the material was perhaps defective or the wrong kind for your application?

Again, I don't know/remember these things today with confidence. Hopefully someone who is using Jeb for Lye will verify or rebuke my selections and provide the proper material for this application?

Call this a BUMP
