CO2 Proof Tubing

This is fine hose. It fit all my fittings and it’s not as stiff as some have said. Yes it’s a little stiffer than cheap airline tubing, but it’s nothing to worry about. It’s specifically designed for c02. Don’t let the other reviewers scare you away, like they almost did me.

Great tubing for CO2. One of the only true CO2 rated tubing packs I e found on Amazon. The rest are just air tubes that don’t say CO2 anywhere on the packs, but this actually says it on the package and you can feel how strong it is when you handle it. If you are doing CO2, BUY IT!!

I used this tubing to replace some cheap airline tubing that I was using previously. The old tubing wasn't CO2 proof and it was apparent. This tubing is 100% CO2 proof based on current performance. It's much stiffer than airline tubing which makes installing it a bit more tricky, but not too bad. When I turned my regulator on I set my bubble counter to 1 bps (bubble per second) and holy cow! The CO2 output into my tank looked to be probably three times as much gas as I had seen coming out of my diffuser when I used my old tubing. On Airline hose, I lost 100 PSI in three days and my PSI almost didn't move after running this CO2 tubing for 3 days at 1 bps showing that this is much more efficient. (Yes, I know BPS isn't exactly an accurate measure of flow but its the best I've got)

Review update!!! As i had stated that "its impossible to make them stay straight.. If you have OCD like i do, you will end up burning couple of fingers trying to heat it to straighten the tubing" After one day of use i have realized that the stiffness adds + points to the durability and works as stated. I've connected this tubing in my co2 system and it being hard, corresponds to the pressure when the solenoid is off. While regular air tubing collapses due to pressure, this tube stays as solid as a rock and does not show any sign of pressure.

Worked perfectly for my freshwater aquarium’s CO2 system! The CO2 hosing is a stiffer material then standard air-line hose, so you need to heat the end of the hose slightly to fit it onto the fittings. (I just use my DeWalt cordless heat gun on low.) I purchased the 25’ length. It came with multiple suction cups to run the hose inside and on the outside of your tank. Would buy again if ever needed.

Excellent product. Super firm and rigid. Will expand to fit just warm up the tip of the hose. Overall great product for my CO2 fed aquarium. Holds nice and does not leak. A+ on the product JARDLI

Hose is fine. Suction cups were missing.

Works great! Not prone to back leakage, handles pressure well, and fits all diffusers I’ve tried.

I'm not sure why other people say it's wrong size. Worked for exactly what I needed it for. Flexible but firm at the same point. Lots more then I needed. I would buy again.

Strong & clear, works well as discribed

Dose the job well

Exactly what I ordered,

The tubing is CO2 proof. It fits perfectly on the regulator and the diffuser. Very happy with this purchase although I find it is a bit pricey.
