How To Use a Keg Coupler

With so many more people installing home bars and draft systems, we at Keg King are getting a lot of questions about how to go about setting up and using keg couplers. All couplers deliver gas pressure to the headspace in the keg while also allowing beer to flow out of the keg spear and into the beer line that attaches to your tap system. This video will showcase how couplers can be assembled with the beer/gas lines and then attached to the keg. To choose the right coupler, check first to see what style of keg the brewery supplying you is using. There’s lots of varieties, but the most common for us is the D-type coupler or the A-type coupler. There are other varieties more common in other countries across the globe. We’ll also cover a few additional coupler attachment options that make assembling and changing over your coupler easy. We’ll show you how you can attach ball lock disconnects to the coupler with post adaptors, adapt the barb fittings with push-in fittings for the beer and gas lines, and make the taller A type kegs fit in our Keg Master Series 4 Kegerators with a Low Profile Elbow Bend. It you are new to serving beer on tap or just interested in how to adapt your coupler with other fittings, this video can show you how. Quick side note: In our opinion, when it comes to adapting the gas side of the coupler with 5/8” post adaptors for ball lock kegs, use either the seal that comes with the 5/8” post adaptor or use the duck bill valve in the coupler. You don’t need to use both at the same time.
