kegland’s duotight fittings are designed to work with their evabarrier tubing. they offer quick, reliable connections, easy implementation, a variety of fitting options and work with double wall evabarrier tubing. these are push to connect and require no tubing clamps. combine these features with their generally low price and this system and tubing are a game changer for kegerator/keezer owners and builders.
as of this posting, the system has no native manifold option available. no need to fear, this post details three duotight manifold options that you can put together yourself.

Build 1 – Convert a Flare Based Manifold to DuoTight
云南快乐十分in my opinion, this is the easiest and cleanest option. it involves sourcing a 1/4″ flare based manifold and installing the proper fittings.
I chose . It features 1/4″ flare fittings throughout. That includes a flare fitting on the inlet port. That’s a bit unique as some models use a barb here, even if the trunks feature flare fittings. Note that this manifold is available in a number of size options. Choose the number of trunks you want, make sure to choose an all MFL model if you want to easily convert it to DuoTight.A look at the input flare fittingA close up of one of the trunk flare ball valves. These also feature and integrated check valve to keep gas flowing the right way.Pressure testing. This held pressure for days before I stopped the test. That’s a testament to both the manifold build quality and the DuoTight fittings. I have completed multiple pressure tests using DuoTight fittings and have found them to be very reliable. Another benefit of the DuoTight system is this economical pressure gauge ( | ). This offers an easy way to double check regulators, check for leaks and more. The newly converted DuoTight ready CO2 Manifold. This is simply a matter of putting a DuoTight Female Flare Fitting ( – ) on each flare equipped ball valve and the input port. Note: DuoTight Fittings and EVABarrier Tubing is available in two sizes, 8mm (5/16″) and 9.5mm (3/8″). I’ve standardized my system on 8mm. Some DuoTight fittings are available in both sizes. Whatever size or sizes you decide on, just keep in mind two sizes are available.Front view of DuoTight Manifold
Build 2 – Convert an existing 1/4″ NPT Manifold Body to DuoTight
I have several gas manifolds. Every model that I have sports 1/4″ NPT threads. Pretty standard for kegerator manifolds, from what I’ve gathered. That means you can swap out the ball valves for 1/4″ NPT DuoTight Fittings. I tried this on two manifolds. The 1/4″ NPT threaded DuoTights feature o-rings. In my testing, I found that I could install these without teflon tape and had no problems with leaks. That may not be the case in all situations so you may have to use teflon tape to seal threads. If you’re wanting to go this route, make sure your manifold body has compatible 1/4″ NPT threads.Here is MoreBeer’s expandable manifold system converted to DuoTight Fittings See: To really get full functionality, you need to add some more DuoTight Fittings. Each trunk needs a ball valve and check valve. The ball valve on the input side isn’t really needed. I have that there because I was pressure testing this setup.Here’s a comparison between the two builds. Although both work, the top version is a whole lot cleaner and more compact.
Build 3 – Tee it up – using DuoTight Tees and Fittings to Build a Manifold
The left-most EVABarrier Tubing represents a feeder line that would start at your regulator and weave it’s way to each keg. From that feeder line, you would tee off for each keg you want to serve. From the tee you would have a DuoTight Ball Valve > DuoTight Check Valve > DuoTight 1/4″ Female Flare Fitting > Flare Based Quick Disconnect (ball lock or pin lock). This photo show’s . This setup allows you to add as many kegs as you’d like, over time. While not as elegant as build 1, this will definitely do the job.
