    These clamps are the only thing I use in my keezer. The extra cost per unit is more than made up for in peace of mind knowing that my system is leak free. 15.7mm is perfect for a 9/16 OD gas line on a 5/16 barb.

    Buying Online at it's Finest

    These clamps were recommended by pretty much everyone. They're high quality and seem to work a lot better than the screw in worm clamps. They certainly look better. The price was much better than the other places I looked.

    They work great, much cleaner than hose clamps.
    A better sizing chart would be helpful.

    Highly Recommended for Clamping Kegging Lines

    Posted by Jeremy on 15th Apr 2015

    These are a must for connecting beer and CO2 lines for a kegging system. It was a little annoying having to research a little to find the correct sizes, but I found that the 15.7 clamps work best for 5/16" gas line, as well as the 3/16" beverage lines.

    5/16" I.D. gas tubing, 9/16" O.D. on a 5/16" barb - 15.7

    I had to guess what size i needed

    Posted by Dan Cirksena on 1st Apr 2014

    TOTALLY absurd to have to guess at what size one needs for the hose they buy. The page with the clamps has no suggested hose OD size that each clamp should be used for. NO ID called out with each clamp, why, where is this handy information?
    Now I had to order a few more than I needed and I still did not get what I wanted for the gas hose I bought - CRAZY.
