1.5'' TC spunding valve

Adjustable spunding valve — hold back-pressure and carbonate naturally in the fermenter.

Screw it onto a 1.5" tri-clamp port and dial in the pressure you want the tank to hold. The valve vents only above your set point, so the CO₂ from active fermentation carbonates the beer in-tank — no priming sugar and no separate force-carbonation step.

Key points

• Adjustable relief — set the pressure the tank holds.
• Natural in-tank carbonation during fermentation.
• 1.5" tri-clamp mount.
• 304 stainless, strips down for cleaning.
