  • Anyone know what this is?

    I've got five 15 BBL brite tanks from Bavarian Brewery Tech with these ports on them. They are 1.5" triclamp, about 6 feet high, there is no penetration into the inside of the tank, and it is not connected to the glycol jacket. They do let out beer when the brite is filled, so maybe it is connected to the bottom somehow. I thought it was some kind of counter pressure sample port, but it still needs a pigtail. Confused and perplexed. Thanks.

    Is it part of a sight glass set up? beer comes out when the tank is full? but not half full? hum... I am confused too. My BBT BBT's didn't have ports like that, i think.

      Looks like it was welded in after the tank was bought.

      My vote for some type of sight glass...maybe there was a ball valve and a flexible plastic tube on it...? Or maybe it does go to the bottom of the tank on a dip tube or something...custom fitting for a specialty serving line?

      Wonky, for sure. Difficult to clean?

          Thanks for the replies.

          Difficult to clean? Not sure yet, but now I'm a little scared.

          I think it is a factory weld as some other ports have a similar weld/look to the workmanship.

          I think beer comes out when it has enough pressure, maybe 1/4 full, I don't remember as I capped the others before filling them.

            Well sure, that there is a kanueter valve port. See whacha do is hook up one of them there muffler bearings and test out yer beverage.

            Kidding I have no idea. But judging by the size of the orfice I would think a sanitary pressure sensor might fit the bill. Unless, do your bbts hold pressure over days? If beer is coming out it could be a weep hole, but that would mean you have a crack in the inside of the tank. Why would they use a sani fitting, perplexing for sure.

              Could it be for a thermometer?
              Is it possible they leak beer because of poor welds?

                They aren't 'bladder' tanks are they?

                A bladder tank has an interior disposable plastic liner that is pressurized 'outside the bag' to dispense.

                Have seen these in continental European brewpubs/small breweries. Several design advantages but several drawbacks as well.

                Could this port be the pressure inlet?

                Obviously just another guess.

                The fitting must have some penetration to the interior somewhere if it leaks beer.

                ??? - Love a good mystery.

                  I believe that is where you put the weed.

                    Hmmm. You could try hooking up a garden hose to triclamp, and shoot water into the fitting... At least then you would know where the it terminates in the tank. Still won't tell you what it does, though.

                      Don't you mean hops hash...?

                      It looks like the clamp fitting that a perlick threads into- well, but on the tank... the hole is about the same size anyway.

                          I agree that it looks added on afterwards....the weld looks really bad.

                            Well if that weld is considered that bad (noting the fact that its unpolished/unfinished) every tank Ive ever worked with must be complete crap, Pub, Spec Mech, Bavarian, a few frankensteins. Now granted tanks have improved quite a bit in 15 yrs. Ohh and to be constructive my vote is a tri-clamp sample port, pulling a sample from the base of the tank and using the distance of the small tube (im guessing) for restriction. The small hole looks to small for a thermocouple or thermometer, plus there would be no need for contact with the beer.

                              Triclamp Thermocouple?

                              This would be my best guess!
