Introducing our new line of adjustable pressure relief valves, commonly referred to as spunding valves.  These valves enable Unitank fermenters to both ferment under pressure and condition beer before transferring to a keg.

Learn More about a Spunding Valve Uses

Scaled | up to 3.5 bbl

The scaled version includes an etched sleeve with a scale between 0-2 BAR, along with a pressure calibrated spring.  This version is perfect for a home or nano brewer that wants to be able to dial in pressures on the fly without having to match the release pressure using a gauge. The scaled version also features a pressure release knob to quickly and easily verify or equalize tank pressure.

Non-Scaled | up to 2 bbl

The compact non-scaled version is perfect for a homebrewer that doesn’t mind taking the extra minute or two to dial in their valve's release pressure using the gauge included with their Unitank.
The kits are designed to hook up the Sspunding Valve to the Unitank blow off cane as shown. Kits include the following:
  • Sspunding Valve
  • Micro Tee
  • Micro 90° Elbow
  • 3x 1.5" TC Clamps
  • 3x 1.5" TC Gaskets
The polycarbonate cup is designed to hold sanitizer so that the tank remains 100% sanitary throughout the course of the fermentation process. 

Lastly, a final note on safety, always leave the fixed-pressure PRV included with the Unitank in place, never exceed the maximum rated working pressure of the vessel at anytime during operation.
  • All 304 Stainless Construction
  • Only for use with pressure rated Unitanks
  • 1.5" TC interface
  • Removable sanitizer cup
  • Easy disassembly for cleaning

Not for use on low-pressure vessels (Chronicals, etc.)

These tire repair reamers work great for plug/other type repairs
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
These tire repair reamers work great for plug/other type repairs. Gone are the days of manually fighting a hand reamer through rough rubber. This is an efficient, neat and clean way to prepare a tire for the repair. Will purchase again as needed.

Got what I paid for.
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
I dropped my drill with the bit installed. It broke quite easily. It was a relatively inexpensive so I can't complain. A higher quality harder metal would have earned 5 stars.

These bits are great. We use them every day e when patching or plugging tires. Having multiple sizes helps us match the bit to the patch we use.

Easy on the hands
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
These make it much easier to ream tires that have been punctured. It takes the stress off of your hands, forearms and elbows especially when you’re plugging higher ply tires.

Handy Tool for Frequent Flat Tire Repairs
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
Good quality and easy to use. As someone involved in emergency services, we deal with flat tires often, and this tool has been really helpful. The bits are sharp, durable, and make the repair process quicker and cleaner. Great to keep on hand for regular use or in a roadside kit.
