Peristaltic pump tubing

+1, aliexpress. Order a bunch of peristaltic and general tubing of all colors. Lifetime supply for the cost of one tube you'd get locally.
In my experience everything arrives quickly in the bay area; ahead of guarantees. I usually buy the 15 days or less ones though, and I'd say it comes in commonly 7-10 days

Yep Pharmed type tubing on the parts that are touching the pump head then silicone for the parts going into your container and tank.

Can you share link to what you bought? @CaseyP @Darkxerox
I have a MasterFlex pump and is looking to buy PharMed tubing. The original one is $260 for 25 feet, expensive.
Thanks!

I forgot what size I got but something like this. I run the same pump as you.
I just bought a bunch more. Aliexpress is the way to go: https://www.aliexpress.com/store/11...e=bestmatch_sort&shop_sortType=bestmatch_sort
Exact size you need depends on your pump. Ideally calc with a caliper, but eye-balling with a ruler works too.
There are some different types you can use, but I personal just do silicone.

25 feet is a lot. 5 feet should last you years.
Pharmed lasts like 30x longer than silicone when used on pump heads. Silicone has lots of what I'd call spalling as it gets wear from friction/heat. It also isn't as gas permeable (somewhat important for some solutions).

What I am using now measures about 1/4" ID x 3/8" OD, branded as PharMed BPT NSF-51. Before this, I tried two different brands, but this current one seems to work better and last longer.
I will try to see if Aliexpress has identical brand/size.
Surprised to see people are using clear silicone tubbing and latex rubber. Wonder how well they work and how long they last.
@Turkeysammich Can you comment if you are happy with the result out of the tubbing you bought from amazon? How long does one cut last?
@Matthew Meyer I am looking to buy two to several feet, I guess. Don't mind to get more if per foot price becomes lower.

Honestly. I run my tubing for a very long time. Like years. I don’t care about the exact amount that comes out. A average is good for what I use it for. I do add silicone grease to the tube and rollers to try to help reduce friction. Dunno if that’s good or bad.
The seller on Aliexpress I got mine from doesn't exist anymore but search for Kamoer PharMed. This seller has a bunch of different sizes, just need to find the one that fits yours.
