About This

• NO MORE BOTTLE BOMBS (or BURPING): Carbo-Caps feature a built-in Pressure Relief Valve (PRV) to naturally carbonate beverages to perfection and release pressure the second it starts to get over carbonated.
• PRECISION CONTROL: The PRV ensures consistent carbonation levels for the perfect fizz in every bottle. When selecting "Color" choose 65 psi for HIGH carbonation, 35 psi for MEDIUM carbonation, or Combo for both.
• ⚠️COMPATIBILITY NOTICE - READ THIS!⚠️: These caps are precision-engineered for 38-1768 thread bottles only. All GT’s Synergy bottles (16oz or 48oz) are a PERFECT FIT. Also works with any 1/2-gallon or 1-gallon growler that uses a 38-1768 closure. Does NOT fit all 38mm bottles. Check before you wreck!
• DURABLE AND REUSABLE: Crafted from high-quality materials, Carbo-Caps are built to last, providing sustainable carbonation solutions.
• EFFORTLESS OPERATION: No need for external CO2 setups, just seal your brew with Carbo-Caps and let the natural carbonation do the work.
• QUALITY GUARANTEED: Carbo-Caps are backed by our commitment to your satisfaction, enhancing your homebrewing experience with reliable carbonation.
