Hands on Review: Kegland BlowTie Spunding Valve!
BlowTie v2 w/Gauge that has been updated to digital, see below for walk through of that process.
Updated: 5/15/2024
A Spunding Valve allows you to maintain a set pressure. If pressure in the vessel exceeds the set point, it is expelled. It generally consists of an adjustable PRV valve, a tee, a gauge and a way to connect to your keg.
Why a Spunding Valve?
There are loads of homebrew related applications for a Spunding valve ranging from pressurized fermentation to naturally carbonating to fixing over carbonated beers and lots more. Check out our resource post on the subject. It’s arguably the go-to resource on the Internet on the subject
BowTie v1 Assembly
BlowTie v1 & v2!
This review covers both the original v1 Kegland v1 BlowTie & v2. Both are DuoTight compatible. The biggest difference is v2 has an integrated gauge, where v1 required an add-on gauge.

But first, more about DuoTight!
Kegland’s DuoTight Fittings are designed to work with EVABarrier Double Wall Tubing. They offer quick, reliable connections, easy implementation, a variety of fitting options and feature amazing versatility. They’re also, generally speaking, very well priced. DuoTights are push to connect fittings and require no tubing clamps.

Hands on Review Kegland BlowTie Spunding Valve v1
The BlowTie Spunding Valve assembly consists of the BlowTie, a DuoTight Tee Fitting, a DuoTight to flare fitting, a DuoTight pressure gauge and two small pieces of EVABarrier Tubing.
The BlowTie is the heart of this build. It has DuoTight Push to Connect connections on both side as well as an adjustment knob to set pressure. Related: DuoTight Hands on Review. Here’s a look from another angle. If you look closely (click to enlarge) you can see an arrow that indicates flow direction as well as + and – signs on the knob to let you know which direction to turn the knob.Connecting the components could not be any easier. The DuoTight system is like the Legos of kegerators.

BlowTie Compared to the Kegland Inline Secondary CO2
This inline secondary (pictured on the left) has been on the scene for a while now. I think it’s an amazing little piece of gear, considering it’s price and functionality. I believe, but am not 100% sure, that it’s also made by Kegland. This photo compares the Inline Secondary to the BlowTie. You’ll notice these look similar, however, the connections are a different size. The inline secondary connection is smaller. My initial assumption was that the BlowTie could also be used as in inline secondary. That’s not the case. Each of these is a purpose built device.
Update: An updated inline regulator has been released that IS DuoTight Compatible. See: Hands on Review Kegland Inline Secondary

Review and Hacks… Hands on Review: Kegland Inline Secondary Regulator! – Use for portable serving!
Utilizing the BlowTie’s Output Port To Use CO2 Produced by Fermentation
Since the the BlowTie has a defined output port, you can use it to capture CO2 produced by fermentation. The “out” side of the BlowTie is a DuoTight connection, just like the “in” side. Use compatible EVABarrier tubing and fittings and you can route outgoing CO2 wherever you’d like. The primary application I can think of for using this is to purge kegs, carboys and fermenters. The pictured setup shows a 10 gallon keg converted to a fermenter. The “out” side of the BlowTie is connected to the liquid out side of an empty keg. That allows incoming CO2 to purge the keg from bottom to top. The lid PRV valve for the receiving keg is open to allow pressure to vent. Of course you could tee the “out” side and flush multiple kegs or vessels using the CO2 produced by a single fermenter.

Using the BlowTie as Part of a DIY Build
This post primarily covers a complete Kegland Spunding Assembly, using Kegland’s DuoTight Fittings, the BlowTie and EVABarrier Tubing but… you can also use the BlowTie as part of a DIY Build
The key to connecting the BlowTie to our standard builds (and probably most DIY builds) is using a Duotight 8mm ¼” NPT Adapter. That connects to a 1/4″ NPT tee. From there you add a small piece of 8 mm EVABarrier Tubing and the BlowTie valve. See: Build a Spunding Valve! – How and Why – for more about putting together a DIY Spunding Build
Hands on Review Kegland BlowTie Spunding Valve v2
The big improvement between v1 and v2 is that v2 includes a built in gauge. This makes for a cleaner setup, is more compact and requires fewer parts.A look at v2’s gaugeSide view. If you look close at the body, you can see a flow direction arrow pointing to the right.Mine has a warning printed on the side never to exceed gauge pressureClose up of the adjustment knobBottom view. BlowTie v2 has mounting holes for easy… mounting.A look inside the DuoTight connector. This is the 8 mm size. To my knowledge that’s the only size option, but it’s possible they also make the larger 9.5 mm size.BlowTie v2 compared to v1Like many DuoTight Fittings these are compatible with Valuebrew’s locking clips. I used to think of those as optional, but now use them on every connection. They provide back pressure on the collar making a firmer connection and locking it in.
Upgrading BlowTie v2 w/Gauge to Digital
Kegland has released a digital gauge option that works with their great inline secondary regulator and BlowTie Spunding Valve. They have also released a DuoTight version.

Conclusions
Like a lot of the gear that’s coming out of Kegland these days… the BlowTie is awesome. It’s super well thought out, feature filled and reasonably priced. I’ve been championing the use of a Spunding Valve for years. It’s nice to see a well made, purpose built device. This is a great piece of equipment. If you still don’t have a Spunding valve the BlowTie is a great option! If you’re trying to decide between v1 and v2, I generally recommend v2 as it’s an all in one unit that’s ready to go.

Troubleshooting Non-Responsiveness
BlowTie Spunding valves feature a diaphragm that can become non-responsive.
The diaphragm can get stuck. When this the case it’s not being properly adjusted with changes to the dial. There’s a short video that Kegland has produced on cleaning the BlowTie Spunding Valve. This process can free a stuck diaphragm.
Leaks? Troubleshooting EVABarrier/DuoTight Leaks
I’ve done several pressure tests with DuoTight Fittings and EVABarrier Tubing. Each test has proven the tested components were leak free. Having said that, it’s entirely possible that you’ll have a leak. This happens with any tubing system, that’s why we… check for leaks. Some tips…
- Check for leaks. Liquid liquids are easy to spot. Gas leaks are a little more difficult.
- I highly suggest picking up a DuoTight Pressure Gauge. You can easily add this to your setup and use this technique for checking for gas leaks.
- If you have a section of EVABarrier tubing that’s marred or damaged, cut off a couple inches to get a fresh end.
- Make sure you’re pushing the EVABarrier Tubing completely in to your DuoTight Fitting.
- Make sure you’re pulling your EVABarrier Tubing out firmly to engage the sealing mechanism.
- DuoTight Compatible Locking Clips can help protect connections and make sure the collar is engaged and properly sealing.
- If you have a particular fitting that won’t seal… contact the seller or manufacturer to get a replacement. A leaking DuoTight fitting is not normal and I’m guessing your retailer will take care of you. Out of the dozens of fittings I have I’ve had 1 that was non-functional on receipt.
Upgrading BlowTie v1 to Digital
BlowTie v1 did not have an integrated gauge. It used a tee fitting to connect a keg QD to the PRV.
