where to buy drink tube hosing?

I believe Lowes has the right diameter. Fish (tank) stores sell tubing, but I'm not sure if they would have the thicker diameter that you're looking for.

hardware store.

hardware, ask for food grade tubing. I got some a while back from a home brewing supply place. iirc, it was 35¢ a foot.

http://www.usplastics.com They sell food grade tubing.

Thanks for all your responses. Would anyone know what the appropriate tube diameter would be for the aqua simple bottle cap? Are these things standardized for platypus?

Thanks again.

Hi Rafi-

I have similar questions. I am planning on turning the squeeze filter into a gravity set-up. I figure I can attach the filter to the clean bag using a tornado tube, but I am trying to figure out how to attach the filter to the dirty bag. It, obviously, can attach directly, but if I want to get any pressure head, I'll need some tubing. Does the aquasimple make it possible to attach the tubing to the filter/dirty bag? The picture makes it look like the aquasimple will allow you to attach to the dirty bag. How do you attach the tubing to the filter? Also, does the aquasimple come with any tubing?

Thanks-
Wayne

I'm not sure if the platy tubing is the right size for your application but the size of it is 3/8" outside diameter by about 0.063" wall thickness. US Plastics will have it, Lowes/Menards/HD might carry it. Something with a slightly lighter wall would probably work as well (provided the OD is proportionally smaller)

US Plastics also sells adapters if you need to adapt from one size to another, I believe they call them reducing couplings.
