Vinyl Clear Hose Tubing - 3/8" ID (Per Foot)

I tried using this tubing for my Fermentech Auto-siphon and it just wouldn't hold a prime. I would give it a few aggressive pumps and it would flow for 5 seconds then quit. I bought some 5/16 ID tubing from Rona and it worked first try. The auto-siphon was designed to work with 5/16 ID tubing. The tubing is here is 3/8 ID as advertised.From fermentech's website:Use the recommended size hose, if available: 5/16x7/16 hose for Regular 3/8 Auto-Siphons and 7/16x9/16 hose for Large 1/2 Auto-Siphons. If you can't find the exact size you may need to purchase a small hose clamp at the hardware store for the connection, if it leaks air.http://www.fermtech.ca/helpful%20hints/help.html

Bought 4 feet of this tubing for my autosiphon which I bought on OBK as well. I had no problem since and it works great!
