The Blow Tie Spunding Valve is used to release excess pressure on a pressurized fermenter or from a keg while doing pressure transfers. Thanks to the large surface area of the diaphragm, this style spunding valve is much more accurate than the poppet style. 8 mm Duotight fittings at both inlet and outlet make this unit perfect for use with EVABarrier 8 mm OD tubing.
The BlowTie 2 features an integrated pressure gauge so you can quickly and easily dial in your pressure setting. The analog gauge is removable and can be swapped out with a gauge of a different pressure range or it can be swapped out for the digital mini pressure guage.
Pressure fermentation is becoming more and more popular at the homebrew level, but in order to do it safely and accurately you need a way to release excess pressure. You'll pressurize your vessel to your desired psi, but once fermentation begins and those hungry, active yeast start creating CO2, the pressure inside the vessel will increase. Attach a spunding valve and set it to your desired pressure, and it will blow off when the pressure gets too high and close up again when it's back to your desired psi.
Even if you don't have a pressurizable fermenter, you may have done pressure transfers from keg to keg during filtering or after fining. During pressure transfers, it's a good idea to have a bit of head pressure in the receiving keg, especially if you're transferring beer that is already carbonated. Having a spunding valve in place will allow you to consistently control the head pressure and give you more consistent results, without losing carbonation in the process.
The BlowTie spunding valve comes with 8 mm Duotight fittings on the inlet and outlet, and we recommend using it with EVABarrier 8 mm OD tubing. You'll also need the flare Duotight fitting in order to attach it to a ball lock or pin lock disconnect. Dialing in your desired pressure is even easier with the BlowTie 2, thanks to the integrated pressure gauge. Simply start with the adjustment knob fully closed, then slowly open it until the gauge reading matches your desired pressure setting.

Price was very reasonable and cylinder works great for my needs (DrinkMate soda maker).
Arrived quickly with a new lid. Just needed to remove labels and clean.
I love these tanks from Corny Keg! This is my 2nd one for my 2nd fridge! Love Dave’s customer service too!
Answered all questions, shipped quickly, working great!
Scratch & dent Corny keg arrived quickly. Packaging was excellent. Keg was holding pressure and clean.
I swapped the tank out so was not able to cylinder. However, others should note that the tare weight was not stamped on the tank and airgas would not take the tank in for a swap.
Everything arrived pretty quickly, had a parts mix up that they resolved super quick on a 1 minute phone call will be buying again!
Boll Lock connect is really hard to push into.
Great customer support, unit doing exactly as hoped.
Ordered a used corny keg, got what I expected. It came pressurized so I appreciate the replaced seals and quality assurance. Successfully pressure fermented a kolsch without any issues.
Dave was incredibly helpful and responsive and made the process easy. Kegs were delivered on time, packaged neatly, and in the promised condition. I am pleased with this purchase and will purchase again!
I called Dave and he spent 30 minutes answering my questions. I am a first time kegger, and need some help on what to purchase. Dave took the time and answered all of my questions.
This is a great company to get all your brewing supplies.
It is incredible! It was easy to set up and it is easy to use. I'm using it to make sparkling water and it comes out cold and delicious! It is also really big so it stores 4 corny kegs really easily
