云南快乐十分Stainless steel Carbonation Cap w/ 5/16″ Barb, Ball Lock Type, fit soft drink PET bottles, Homebrew Kegging

云南快乐十分this is a stainless steel ball lock carbonator cap that is typically intended to use with 1l and 2l pet (soda type) bottles for force carbing and transporting beer (soda, etc).  why does it include a barb?  i have no idea, but it comes in really handy for this purpose.

IMPORTANT UPDATE: 云南快乐十分I have heard that this fitting no longer works with BOTH liquid and gas ball lock QDs.  That is an important feature for this project.  I have since un-linked the original fitting.  Photos of the original fitting, are shown throughout this build.

Consider these alternatives,  Specifications Can Change: Check product descriptions for current description and specifications to make sure these are designed to work with both liquid and gas QDs.

cln_img_9641A photo of just the carbonator capcln_img_9644A carbonator cap would typically work with a gas QD and this does.cln_img_9642However, it also works (easily) with a liquid QD.  Not sure why it’s designed like this, but it is and this is another important feature.cln_img_9646To adapt the Keg and Carboy Cleaner for Ball Lock draft lines just attach the stainless carbonator cap to a length of 1/4″ ID tubing (the shorter the better).  Attach the unused end to the smaller of the two included barbs (intended for cleaning tubing) and whammo… you’ve got a line cleaner.  I didn’t use any clamps.  Things held together fine and disassemble for easy cleaning.

cln_img_9654云南快乐十分I use a piece of 1/2″ ID silicone tubing over my faucets to return cleaning, rinsing and sanitizing solution back to the Keg and Carboy Cleaner’s basin.  Recirculating means you can run this for a long time (according to your cleaner’s recommendations).  You may also save money by using less cleaner and sanitizer.

云南快乐十分this has the advantage of cleaning everything in your draft system.  it cleans the faucet, the shank, the quick disconnect and the tubing.  some line cleaning pump designs i’ve seen have you removing the beer nut and placing the hand pump apparatus directly on the shank.  that’s some work disassembling and reassembling and it also skips the line and quick disconnect.

cln_img_9657Here is a photo that should hopefully give you an idea about flow rate.  If you look at my original Draft Line Cleaning Pump Build云南快乐十分, you’ll see that I don’t believe you need a gushing fire hose-like flow rate.  The important thing, in my book, is touching all parts and constant flow.  Along those lines, if you’re looking for your draft cleaning pump to resemble a pressure washer, I’d suggest looking for something different.  I spent no time on trying to increase flow for this build.  It’s going to depend on your line length and where you place the Keg and Carboy Washer in relation to the top of your shank.

cln_img_9660A look at the 1/2″ ID tubing over my Perlick faucetcln_img_9666The Keg and Carboy Washer can be a bit unwieldy to pick up when full.  You can drain a good bit of liquid off by redirecting the discharge tubing to a bucket.

cln_img_9649I have added this switch to my Keg and Carboy Washer setup.  It allows me to easily turn the pump on and off without plugging and unplugging it.  This switch appears to be similar although not the exact same part number… [].  You may want to add a  and for safety, always read and follow manufacturer’s warnings.

Alternative for Pin Lock, Sankey and Ball Lock Systems.  I know of no similar Pin Lock style carbonator cap.  You get nearly the same benefit by replacing that with a .  Remove your MFL Pin Lock QDs and attach to this fitting.  The only thing you’re missing is including the Pin Lock QDs in the cleaning process.  This would also work for Sankey and ball lock setups, you just need to have 1/4″ MFL lines.

Prior to getting a Keg and Carboy Washer myself, I consistently heard great things about it.  I can confirm the praise.  This is a great piece of equipment that saves me time.  The additional ability to clean lines with little additional expense sweetens the deal further.  The Mark II Keg and Carboy Washer is one of our Top Finds.

    云南快乐十分has anyone else had to take the “guts” (post and spring) out of the quick disconnect to actually achieve flow to the beer lines?

    i have modified my recirculating draft clean setup to flow backwards (the opposite of the flow of beer when you’re pouring). the reason for this is that it allows me to flow from larger tubing to smaller tubing, which more adequately cleans the faucet. if you flow the normal way, it is very likely that your cleaning fluid of choice doesn’t hit all the spots on the faucet because the vessel the fluid is traveling through essentially widens from 3/16″ to 1/2″ or so. it also appears to increase pressure which some people are worried about, but rest assured the chemicals just require movement, not super-speed movement.

    to do it, i simply bought a cheap $2-$3 plastic half inch npt fitting from my lhbs to attach the piece of silicon tubing too just like in this guide. i still use the 5/16″ barbed qd to attach to the keg’s “beer out” post, it just doesn’t connect to the pump anymore.

    i can’t imagine that’s really a 5/16″ barb, right? i know that’s what aliexpress says but if a 1/4″ piece of tubing fits over it, it’s got to be much smaller than that, right? i’m thinking it’s the same size as a beer qd barb…

    yes my pump died too, need suggestions for a replacement? mine lasted 4 years, so not really complaining, but would rather just buy the pump instead of all the plastic accessories

    i need a replacement pump for my markii as well. my impeller lost a fin and it gets wonky… it can work, but it takes a lot of effort to get it spinning…. and then it’s noisy. a new pump is needed….

    云南快乐十分help! any suggestions? i tried to ask the manufacturer, but no help there… never replies to emails.

    this! i have a similar set up using the pump of the mark keg washer but i place it inside a bucket as it uses less cleaner in the sense that the volume of the solution needed is less to keep the pump submerged. also, i’ve created a split in the line and have three of these awesome carbonator caps which allows me to clean all my lines at the same time. my lines are 8ft long and the pressure from the pump is pretty good. check out my setup in action:

    also, this is why the barb is included and why it’s awesome that you can connect both gas a liquid ball locks

    enjoy.

    i liked my mark ii until the pump broke, then when i got it fixed the impeller started coming loose every time i used it. the pump is garbage and can easily be replicated with a trip to amazon.

    云南快乐十分nice write-up. fyi the hose barb on the carbonator cap is for attaching a short length of hose to go to the bottom of the bottle so you can do beer transfers without introducing any oxygen. also helps with beer-line cleaning. this video (not mine) shows some cool tricks:
