This was exactly what I needed in order to tap the Stella keg I had! Unfortunately they shipped me a D tap but when I called and pointed out my issue they responded exquisitely! Emailed me a return label for the D tap and in another day and 1/2 I had the proper S tap at my door!! Great response from them. I'll go back and do business with The Beverage Factory again for sure!

Question:
Is this low profile keg coupler compatible with Euro brands such as Paulaner, Weihenstephaner, etc.?
by Em on July 11, 2019
Answer:
This coupler fits S system kegs. The 2 mentioned require an A system coupler.

Question:
Will the Perlick Lo-boy fit on a Guiness 1/6 barrel?
by Nick on October 29, 2020
Answer:
Hello Nick, the Perlick lo-boy coupler will not work with a Guinness keg, as Guinness requires a "U" system coupler, and the Perlick lo-boys are currently only available for "D" and "S" systems.

Question:
The lo boy s coupler seems to not sit nicely on the teeth if my stella keg. I have to force it down which then shoots out beer. How do I get the bottom of the coupler to sit higher so it can sit under the teeth of the keg before twisting?
by Chris on June 16, 2026
Answer:
The coupler should sit fully under the keg lugs before twisting and shouldn't need to be forced. If you're having to force it or beer is spraying out, could you send us a photo or short video of how the coupler is sitting on the keg so we can help identify the issue? support@beveragefactory.com
