I originally ordered from SS Brewtech, but their shipping is all messed up through the USPS. I was afraid to order on Amazon fearing poor quality. Morebeer had them, shipped quickly, and they are high quality.
One small advantage I noticed with this barb is that I can wrestle it off the tubing easier than some other barbs. Others hold so tight to require slitting with a knife to remove. I'm clamping the tube around the barb anyway, so I prefer the ease of removal when I want.
I needed some new hoses for our Blichmann 3.5 BBl system. I did not want large hose barbs as they cause more chance of large spills, since we do not care that it takes more time to empty a large vessel through 1/2" hole rather than a 1" hole. Also the yeast at the bottom of the fermenter remains undisturbed for the most part, this works very well for us.
I recommend you try this sometime.. David Roesch, Crafty Canary Brewery
