A weldless bulkhead is used to provide a liquid-tight port into your brewing vessels. This is an alternative to having a coupling or spud welded or soldered in.

Our new line of "True Bulkheads" were completely redesigned from scratch. The entire homebrew industry is flooded with makeshift bulkhead designs that are only a small step up from the DIY parts you'd find at a hardware store. While we were confident in the performance of our previous bulkheads made from off the shelf parts, the new True Bulkheads solve several shortcomings and look sharp in the process.

All varieties of True Bulkheads:
  1. Use a huge hex size with a machined O-Ring containment groove (gland). When used with an oring, you can tighten the bulkhead with gorilla strength for stability and the gasket will not budge or get damaged.
  2. Are machined from a single piece of hex bar stock for less places for crud to hide.
  3. Rely on an exterior locknut to make the gasket squeeze. No more trial and error with various shim washer thicknesses and playing teflon tape Olympics.
  4. Accommodate vessel wall thicknesses up to 3/8" or 8mm thick while still leaving enough male thread for a ball valve or any other female threaded fitting.
The theme here is that these bulkheads are in a different league and we think the pricing is unbelievably reasonable for what you get.

This particular truebulkhead has a 1/2" tube compression fitting on it. It is also of a "bore thru" (bored through) design meaning that it allows the 1/2" OD tubing to pass completely through the fitting if you wish it to. This fitting is primarily used for installing a HERMS coil into the side of your hot liquor tank, but use your imagination. We also have this fitting in 5/8" tube compression elsewhere.

We offer a choice between stainless and nylon compression rings/sleeves.

  • Stainless Ferrule: This is a set of rings/sleeves/ferrules that slip over the tubing, but behind the compression nut that get squeezed onto the tubing when you lock the nut down TIGHT for the first time. This process permanently crimps the rings to the tubing though you can still remove the compresison nut and tubing (though the nut is now captured). This option is more difficult to use and requires a lot of torque to set, however it is the better mechanical option where a lot of stress is put on the connection.

  • Nylon (AKA Delrin) Sleeve: This option replaces the pair of stainless rings with a one-piece wedge ferrule made of a tough, high temp, food grade plastic. It seals well with minimal tightening on the nut (hand tight plus a quarter turn), never attaches itself to the tubing permanently. Although it is plastic, it does allow for many disconnection cycles without wearing out. They are successfully used on HERMS coils where the full weight of the coil is supported by the compression fittings.
Hole Side 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.

Install Notes:
  • Drill a clean 13/16" diameter hole in your pot taking care to avoid any wall contours that may prevent the interior hex from sitting flat on the inside wall of the vessel. It is also important to remove any sharp edges or "burrs" from the inside edge of the hole, otherwise the oring can get torn. Insert the threaded portion of the unit through the hole from the inside of your pot or keg with only the oring in place. On the outside, install the metal washer and locknut and snug everything up with a pair of wrenches. Hint, it's best to hold the interior hex so that one of its points is facing up. It's better to hold the interior fitting still and tighten the exterior nut to protect the gasket/oring.

5 of 5 Great products, excellent craftmanship April 27, 2020
Reviewer: Robert J Athanasidy from Westcherster, NY United States  
Appalled anyone could trash these items. I have built two HERMS/RIMS systems and find these are the best solution for a tight, clean transfer. Building another today.  Great customer service also.  Keep up the good work!

1 of 5 Keep getting ripped off by these brew companies. March 10, 2020
Reviewer: Jacob Butchko from Port Byron, NY United States  
Don’t waste your money buying the wrong parts. 1/2” weld less tube bulkhead fitting with 1/2” NPT.
It’s a junk fitting that won’t work to make a coil because the “NPT” isn’t tapered and will never seal on a valve or a hose.  And the ferrules are not interchangeable with the correct fitting so have fun hack sawing them off your coil when you find an American to sell you the right fittings.

Brewhardware.com Response:

First things first, you never called or emailed me to get product support on this and just left a nasty review.  We stand behind these products 100%. The 1/2" threaded side is absolutely a standard NPT taper and seals perfectly with all 1/2" NPT female fittings. We have sold over 5000 of these true bulkhead fittings and all of a sudden you are the first person to find out how terrible they are? We install them on our $2000+ brewing systems. Did you ever stop to think that the fitting you tried threading on is out of spec or that you cross threaded?
