- • Not ideal for: Users who do not use PET bottles or lack ball-lock connector systems
Stainless steel cap designed for CO2 injection into PET bottles using ball-lock disconnects. Compatible with gas-side and liquid ball-lock connectors for quick carbonation.
Fast Bottle Carbonation – With gas-side ball-lock connection
Cap attaches to PET bottles and connects to a gas-side ball lock disconnect, allowing carbon dioxide to be forced into the liquid under back-pressure. The direct connection bypasses need for complex adapters when matching ball-lock systems.
Bottles carbonate quickly after connection, so small runs of soda or beer are ready in minutes rather than hours. Useful when preparing drinks for gatherings or finishing small batches.
Durable, Food-Grade Construction – Thanks to 304 stainless steel
304 stainless steel resists corrosion and endures repeated contact with acidic or carbonated liquids, maintaining structural integrity over time. The material is specified as food grade for safe beverage contact.
Expect a long service life and safe handling when working with consumable drinks. Durable construction reduces the need for frequent replacements in a homebrew setup.
Versatile Beverage Use – With compatibility for gas and liquid ball-lock connectors
Designed to work with both gas-side and liquid-side ball lock connectors and to fit PET bottles for back-pressure filling, enabling a variety of connection methods. The cap supports the mechanics of forcing gas into filled bottles for different beverage types.
