Another variation of our True Bulkhead series, this one has a 5/8" compression arrangement on the inside and we include a diptube to go into it.
Instead of buying a separate weldless drain bulkhead and dip tube compression assembly for your Hot Liquor Tank (HLT) or Boil Kettle (BK), get it all in one compact piece. What's more is the 5/8" OD dip tube has a larger than 1/2" inside diameter for absolutely no restriction. This becomes more important when you integrate a pump into your brewery. Even if you don't have a pump yet, be smart and buy the high flow diptube the first time.
Instead of including the typical metal ferrule rings to compress against the tubing that is typical of all compression fittings, we use a Nylon/ Delrin high temp and food grade plastic. The advantage to doing this, in this particular application is that you get a seal by simply tightening the compression nut hand tight (or a quarter turn more than that if you have delicate hands ;-)). Metal ferrules require a ton of torque to initially seal and the ring and removing for cleaning requires a wrench.
Note: if you're looking for a dip tube for a flat bottom pot, please consider the weldless bulkhead with elbarb diptube as a better/cheaper alternative.
Options: If your hole is closer to 13/16" the standard oring seals great. If your hole is a bit over-sized, right around 7/8", we can include an additional thin oring that will keep the fitting centered in the hole while you tighten it up. If you have no way of accurately measuring your hole, the threads of a 1/2" male NPT fitting will be snug in a 13/16" hole and wiggle side to side a bit in a 7/8" hole. When in doubt, select 7/8". You can remove the extra oring and try it but you'll have it in case you need it.
Instructions:
Drill a clean 13/16" (ideal) or 7/8" (a little loose but OK) diameter hole in your keg or pot taking care to avoid any wall contours that may prevent the silicone gasket from sitting flat on the inside wall of the vessel. Remove the thin locknut and SS washer from the assembly insert through the hole from the inside. Slide the SS washer on from outside, followed by the locknut. Wrench tighten. It is nearly impossible to overtighten because the oring stays captured in a groove on the inside and is not at risk of bulging out.
The last step is wrapping the end of the threads with some teflon tape and then a ball valve of your choice. Of course, you can thread on any kind of fitting with 1/2" female threads as an alternative. Note: the ball valve will NOT make contact with the exterior locknut in this design. The seal and locknut assembly is completely separate from the ball valve attachement. You will see a section of threads between the nut and ball valve and this is normal.
The dip tube height may need to be trimmed in some cases. In a hot liquor tank, you want the opening of the tube to sit about 1/8" off the bottom. In a boil kettle, you can rotate the diptube so that the opening is about 3/4" off the bottom offset from center to leave some trub in the center dish. To leave even more behind, reverse the diptube so the short end is in the compression fitting.
