Setting up your draft beer system in small refrigerator can be a challenge — but it's not impossible. This Perlick low-profile keg coupler is designed for tight clearance installations.
The keg coupler's job is to connect your CO2 tank to the keg so the gas can push the beer up through the beer line. The bottom of the coupler attaches to the keg valve, and the beer line and air line slide over the horizontal hose nipples and secured with screw clamps.
With 100% stainless-steel contact, you can be sure that this beer coupler will last for a very long time, and that unwanted chemicals will not enter your beer and taint its quality.
With standard keg couplers, you need a few inches of clearance above the top of your keg. But with a low-profile design, this keg coupler only sticks up about ¾ inch above the rim of the keg. So you'll have an easier time installing and operating your keg setup in limited space.
This keg coupler uses the US Sankey (D System), which is the valve system of choice for just about all beers brewed in North America, including Budweiser, Michelob, Busch, Miller Lite, Coors, Killians, Sam Adams, Labatt, and more. To be safe, check our handy coupler list to find out which system your favorite beer calls for.
This handy beer coupler is a great choice for both home and commercial bars.

Excellent replacement part.
Excellent, albeit expensive product. Replacement of a faulty previous Perlick Lo-Boy. Did the job perfectly!
Perfect fit in my kegerator. Works wonderfully!
Generally good product could use improvement for easier tapping of kegs
Good solution for limited space kegerators. Would be better if tapping a keg was not as difficult to operate as the traditional style with a handle to activate the probe.
I used them but they were very hard to put on because of the height of my keg box. Had to use the tips of my fingers. With hoses running over the kegs edges the keg had to be inside the box before I could put them on. Very difficult in my application.
Works Great
Great for space limited kegerator’s.
makes room as I needed
Gives me the headroom i needed. Not for amateurs though, makes a mess the first few times you tap until you get the hang of it even still it does spray every time.
Very unhappy!!
The coupler they sent me has a leak in it, it waisted my whole brand new CO² tank. I've contacted kegworks and asked them for a replacement coupler. They told me that they would have a Draft specialists be in contact with me. I still haven't heard anything from either Kegworks or the specialists...
Definitely worth the extra money; well constructed.
Really good low profile coupler for reducing headroom in your kegerator. Simple to install with a positive lock position. Easily accepts pin and ball lock adapters.
Everything was good
Awesome!
Works great. Allowed me to use a commercial keg in my homebrew setup.
Great Quality
Works great, best price too!
Low profile coupler
I have a keg of bubbly water in my kegerator. The keg sits on the shelf so a normal coupler is too tall to close the lid. This one works perfectly! Thanks so much!

Doesn’t fit on a sixtel keg
It would be perfect for what I needed, but unfortunately it doesn’t fit on a sixteen keg.
Great product - really handy!
Kegerator space. As advertised by the seller, you can fit two quarter barrels in my new kegerator - they neglected to say tapping them would be a challenge! That’s where these couplers come in very handy. Frees up the headroom space and have a nifty design. Working great!
Buy these now!
Fantastic, my other low profile we’re wearing out and allowing beer to creep into the gas line. Easy to install
Great!
Great product, works exactly as needed

Works great. Low profile is the way to go.
