dosers and tubing

Acronuts · Feb 25, 2015

I recently purchased a Kamoer doser and realized that the tubing it comes with is not enough to run lines to each container and then to my sump.

Where can i get specialized tubing? My local hardware stores don't carry anything that measures 1/8 inside diameter or in metric format 3mm.
Can anyone direct me to an online site that sells this type of tubing?

I only looked on amazon, so there may be others...

So, this is the 3mm ID

By my calibrated eye, that tubing looks to be bigger than 3mm ID. For the $3.00, I'd pick up the 25 feet of 1/4 inch tubing from HD....that has 0.170 ID.....HERE

Yeah only the tubing in the doser head matters... The rest can be simple tubing

I tried the 1/4 and it slides nicely in but does not hug the connecting piece tight. I thought about zip tie but I can't seal it tight enough to not cause a leak in the line.

Agreed but unfortunately the unit comes with these male pieces where the 3mm/ 1/8 tubing is the perfect size. Some suggested that I buy a connector that will downsize it to match the 1/4. but since i can find the rt kind why try to add something else that can get clogged IMO.
