This  kit includes a Ball Lock Spunding Valve,  professional 1 BAR tri-clamp PRV, and a bottle of CellarScience FoamAxe krausen reducer. Intended for use with the BrewBuilt Pressure Pack to enable the X1 Uni Conical to be used for pressure fermentations.

The ball lock spunding valve features a 0-15 psi pressure gauge and a hand adjustable blowoff for adjusting the pressure setting. The 1.5" T.C. PRV provides added safety when fermenting extra-large or high gravity batches where krausen may reach the lid of the fermenter.

The spunding valve installs on the gas in ball lock post of the Pressure Pack 4" T.C. lid. The tri-clamp PRV replaces the Blowoff U Barb to seal the conical and protect the unit from over pressurization.


  • Ball Lock Spunding Valve
    • Stainless Torpedo Keg Gas-In Ball Lock
    • Pressure Gauge (0-1 BAR / 0-15 psi)
    • Hand Adjustable Blowoff

Caution: With our pressure fermentation kit attached to a BrewBuilt X1 Conical unit there are three points of pressure relief: the relief built into the lid, the relief on the spunding valve, and the commercial PRV (Pressure Relief Valve). You should always use FoamAxe to reduce Krausen production in the fermenter. If you do see krausen exiting any of the pressure relief valves, you need to immediately release the pressure in the fermenter, clean the relief valves, and ferment the rest of the batch without pressure.
