Purchased three of these for my keezer. Two work but I just found one is leaking. Found about a pint of beer had leaked out before I caught the problem. Just read there are machining issues with these. Good luck if you purchase these! William's Brewing Responds: Sorry about this, we have sent a replacement at no charge for your defective one. Thanks for your business!

Works Great

Review by Greg on 12/13/2019

I brew Belgian Ales exclusively and carb to 3.25 volumes. This requires approximately 20 psi of CO2 on keg at 40 F. I am new to kegging. I have a 4 foot beer line with a picnic tap. This poured foam until I got this flow control ball lock.Certainly better than 18ft of beer line as per Mike Solty's calculator. This has allowed me to balance my system easily. A simple, elegant solution

Loving these

Review by Brian on 11/5/2019

Don’t believe the last review about how they’re too flow restrictive. I’m using bev-seal ultra with John Guest fittings. ~8 feet of tubing, and I used to have to use ~20 feet. Great pour in ~15 seconds. I could cut the thing shorter if need be, but it’s great as is. Of course ultra bev-seal has a much lower resistance than your typical crappy vinyl tubing. Maybe some of these vary during manufacturing, but mine is wide open right now, and giving me a great pour. Pressure in keg is at 14 psi with a temp of 40-43F. Flow control Rototap faucets set to wide open. Give these a try for greater control!

Not for Keezers or Kegerators

Review by Craig Hairrell on 9/22/2019

I bought three of these for my keezer. Despite being wide open and using 2-ft lengths of large diameter tubing, I was unable to pour pints lower-carbonated beers like porter in under 30 seconds. Even wide open, these introduce a restriction. I wrote to Williams customer service and they replied saying: "We find they work best on keg faucets, where there is no tubing at all. They do restrict flow more than regular ball locks, and are probably not the ones to use with low carbonation English Ales. Other than that, people love them on Mini Kegs and as snap on ball lock faucets. We have a lot of customers now who do not brew at all, but dispense commercial kegs, which can sometimes have high carbonation levels. So they work in this situation also. We are also talking to Kegland about making them more universal, that is, able to flow wide open easily, and then tighten down, rather than the way they are today, which is partially restricted even at the largest setting."

Work as expected

Solid and well made. For now, one week into its use, works as expected and it is much better than flow control at the faucet. Great design job!
