Will these work as my dosing pump conectors?

[Gungo]

I got an used doser and all the dosing tubing connectors were gone. Will these work as replacements? I am really bad at tubing dimensions...

Amazon Link

This is what I am looking for but I don't want to pay 10 bucks + shipping for a set.

You need to know the diameter of the tubing on your pump. They are not all the same. That said, most of them use standard airline which is 3/16 in. So the one you found on amazon is probably too big (1/4 in.). Here is a 3/16 in. option: Amazon.

The tubing says DI= 2.5mm. Do you think it will work with the link you shared?

I think 3/16 will work, but you might need 1/8 inch fittings. You could go to home depot with your tubing and try different sizes. They will probably only have brass, but you can at least confirm the size and then buy plastic ones online.
