ALEGI 100 Feet 3/16-Inch Professional Flexible Silicone Air Tubing for Aquariums, Terrariums, Hydroponics

Love this stuff. Stays supple so far. Run 30 aquariums with it in my fishroom. Black so no algae issues.

Hasnt hardened up, has stayed pliable and easy to remove/insert.

Flex

Works well and doesnt harden over time. Only con is that its more flexible\soft so easier to crimp\pinch.

This stuff is amazing, they sent me so much of it and it was so cheap I'm thinking of all kinds of other uses for this stuff It doesn't smell one bit, ok it smells like 1 bit but I am super dooper sensitive to smell so I can smell this stuff slightly, it doesn't smell at all like the plastic hose material you would typically expect it to smell like, it smells fine, trust, give it like 1 day and it won't smell at all. Silicon, much better material. Thanks for making the product that I had expected this to me from the reviews and such.

This is great air tubing for low pressure applications. It's so much easier to work with than vinyl or polyethylene tubing. It fits all of the 1/4" connectors I've used it with so far. I wouldn't use it with press-fit connectors though. For kicks I used it for a high pressure spray irrigation line to see if it would burst or even stay on the connectors. It held up to about 90psi. I ended up with a failure with the PE tubing, not the silicone tubing. YMMV

As described

Works great. Size is perfect, small enough to fit tightly but thick enough to pass a lot of air through. Line stays in place on bubblers.
