CO2 tubing

Can anyone tell me where I can buy CO2 resistant tubing? I had some that came with my CO2 diffuser and it was always too long, so I cut it today to get rid of some excess. The tubing is old and was yucky looking so I threw it away thinking I could buy more from Drs Foster and Smith, but after searching their website I couldn't find any. Does anyone know?

 

I just buy 10 feet of clear tubing by python at my lfs for a little over a dollar and replace when needed. Don't know if that type of tubing exist

 

I guess I'll just have to dig it out of the trash then.

Here's several places:
Marine Depot's 4/6mm ID/OD CO2 tubing comes in three colors. It's semi-stiff:
black:
green:
blue:

I use Tygon Lab tubing also in 1/8" ID (TT18F) and 3/16" ID (TT316F). It stays solf and flexible:


US Plastic Corp. sells the Tygon Lab tubing as well:

I use the semi-stiff Marine Depot Tubing fron my regulator to my check valve. Then from my check valve to my diffuser/reactor I use the softer Tygon Lab Tubing.

Silicone tubing allows a good bit of CO2 to leak through it's pores. Look at the silicone tubing about CO2 permeability in this Cole-Palmer tubing chart:

No, Isabella didn't tell me about this site; Butterfly did. I didn't know anything about this site until yesterday. Thanks for the welcome!

 

O ya, could have been her too. Glad your here, hope you like it.

 

It's good to have Left C with us. Some expert advice about planted tanks is always welcome here And it is certainly very appreciated

I thought Left C has known about this website, and that is why I never mentioned it to him. I guess I thought that since Carol knows people on Plant Geek, they all know about Fish Lore. I was surprised to learn Left C didn't know about it up until now.

 

I guess I'm like Commander Cody sometimes. I'm lost in the ozone.

 

LOL hehehe ;D

 

Thanks Left C! ;D I can't believe Drs Foster and Smith don't have them.

I wonder why the Dr.'s sell silicone tubing with their CO2 kits?

Here's a good place to get CO2 tubing and it's a good price too. It 70¢ per foot: He also carries many other CO2 products.
