⚡ At a Glance
- • Sealing Performance: Stainless steel construction with 5/16 inch barb ball lock CO2 coupling, creates a counter-pressure seal for bottle filling
- • Best for: Homebrewers and soda makers who fill bottles by counter-pressure and want to minimise oxidation
- • Not ideal for: Users seeking a complete electric soda maker rather than an add-on filling cap
Stainless steel carbonation cap with a 5/16 inch barb ball lock CO2 coupling for counter-pressure bottle filling. Suitable for carbonating soda, beer, fruit juice and water.
Secure, low-oxygen transfers, thanks to 5/16 inch barb ball lock CO2 coupling
Ball lock CO2 coupling connects to 5/16 inch tubing and allows gas to pressurise the bottle, balancing pressure during filling to prevent foaming and backflow. Counter-pressure filling keeps headspace oxygen low while liquid flows into the bottle.
Minimises oxygen pickup during beer transfers and helps retain carbonation when filling soda or juice, giving more consistent results bottle to bottle.
Durable construction, with stainless steel body
Stainless steel resists corrosion and stands up to mechanical stress better than many plastic alternatives, maintaining a reliable seal under repeated use. Metal construction also handles typical brewery cleaning and handling without obvious wear.
Provides a reassuring feel during use and should last for regular homebrewing sessions, reducing the need for frequent replacement.
Hassle-free upkeep, thanks to included spare O-rings
Spare O-rings allow quick replacement of worn seals, ensuring the coupling and cap remain airtight without delay. Simple O-ring swaps restore sealing performance without specialised tools.
Keeps downtime low and reduces the risk of leaks during busy carbonation runs, making maintenance straightforward for hobby brewers.
