Kamoer X1 to 1/4” tubing

[Avocaadotoast]

I actually had the exact same problem as you, the kamoer x1 pump didn’t come with an adapter to change the size of the tubing, but I found this on BRS https://www.bulkreefsupply.com/dosing-pump-tubing-adapter-bubble-magus.html

This fits directly on the kamoer pump, and I attached it directly onto blue RO tubing.

The other option would be to not use RO tubing for dosing lines.

They sell dosing line that is 1/4" OD, like RO tubing so that it works in all your push in john guest type fittings on your dosing containers while it has a 1/8" (3mm) ID, so it still fits over your dosing pump barbs/nozzles. One dosing line, no adapters/fittings needed.

They even sell it at Home Depot, a 20 foot roll is about $4. it only comes clear though, no colors.

I just have the one that I found when I posted this thread, which went inside a barbed fitting which I don’t especially like.

So I just started looking at them again and I just ordered some 3/16 to 1/8 barbed reducers from Amazon. I don’t know if it is the right size or not but it was said to work from a user on this thread so I’ll try it out.

If you want to wait until June 2 -June 6 (the delivery date) I will let you know if they worked for me.

Yes do let us know how it works out.

This sounds ideal, I'll check it out.

1/8" ID 1/4" OD Clear PVC Vinyl Dosing Tubing

If rodi tubing doesn’t fit on the barb why would the same dimension vinyl tubing work?
Also, I try to avoid using vinyl tubing when I easily can because there are reports that certain types can leech tin into the water.

So when I got home I checked, and the only fitting that it includes is the one the goes from the head to the provided 3mm ID tubing. I tried seeing if a 1/4 tube would fit over that fitting instead of the supplied tubing and the fitting is too small.
When I look for barbed fittings they’re not mixed with one side being metric and the other being standard.

Of course @CoralVue uses some really obscure impossible to find tubing with these pumps (I looked forever trying to find it with no luck) - I ended up taking the little piece of tubing that’s included in the bag and jam it into a larger standard size tubing (these are silicone, a little easier) then snip of the end to make it fit tight.

It's not the same dimensionally. Different ID's. They have the same 1/4" OD, but their ID's are different.
This dosing tube has a smaller ID than RO tubing, so it fits on the smaller barbs, where RO tubing doesn't (reliably)
This tubing has 1/8" or 3mm ID, where RO tubing has an ID a little over 4mm.

Just need to recalibrate your dosing pump if changing dosing line ID.

I was not aware of the tin issue with vinyl tubing though... interesting.

looks like I need to throw a chunk of this tubing into a container of RODI for a while and then send that off along with my next ICP test. I'm thinking that would confirm whether or not it's leaching any tin or not.

FYI. you can find this same vinyl tubing with either a 3mm/1/8" ID and they also make it with 4mm/.170" ID, which is very close to RO tubing. All with 1/4" OD, so it works in the push in fittings like RODI tubing. Just pick the one that fits on your particular doser nozzles and you are all set.

For many years I have thought the id of rodi tubing was 1/8(.125”) and after reading your post I just looked online and it seems that it is actually either .142” or .170” (I am seeing both listed on different websites.

As for the tin leeching, I have never had it happen personally and I’ve just read about it. I do use some vinyl tubing in my system for long runs through my ceilings for my AWC but at the time I didn’t know about the possibility of tin leeching. My icp test never came back with elevated tin so mine didn’t seem to do it, or it’s old enough that anything that was going to leech out already did. I just try to avoid it now when possible.

Sorry for reviving this, but did you end up testing the reducers? My x1 didn't come with the plastic barbs and I'm having trouble finding a solution.

I dont remember if the reducers I bought off Amazon ended up working. When I get home this evening I will look at the pumps and see if that is what I have on them.

I ended up ordering some from mcmaster, i believe they were 3/16 to 1/8 reducers so I can use 3/16 tubing.
