Feelers16mm ID x 20mm OD High-Strength Silicone Tubing Thick Food Grade High Temp Pure Silicon Tube High Temp Home Brewing Winemaking Silicone Hose Tubing, 3.3ft Length

Tried it since it is the correct size. Not compatible with fuel containing ethanol. The material will swell up to 2x its original sizing.Good quality tubing though, extremely flexible and kink resistant.

Correct size for most squonk bottles. Works great!

Good quality silicon hose. Worked great in my application and was very flexible and good quality.

Seems to be good quality and worked for me. Time will tell.

I’ve got hose. The extra mm of outer diameter actually makes a two to three fifths tighter and sturdier seal than its 4mm counterpart

This was the perfect size for my Harbor Freight media blast cabinet to replace the very stiff vinyl line or whatever it had. I probably should have went with a reinforced silicone hose rather than this as it will kink, but it works and flows great as it it. Rarely do I move to a position where it does bend or kink on itself, so it's not been any real concern to me. I punched a hole in the side of the cabinet and used a conduit grommet to feed it into the chamber.

The original silicon hoses, where the connected to the heat plate had hardened and cracked after years of use. I was able to disassemble and replace all the hoses inside and not it works again without leaking.

Used this tubing to do the Silicone bed mod on my Sovol SV06+. Worked great and now I can level my bed to +-.1mm easily!
