Designed with simplicity and performance in mind, it provides a secure, leak-resistant connection between your CO2 line and keg’s gas post—whether you're carbonating or serving.
Direct CO2 Line Attachment
This connector features a built-in 1/4″ barbed fitting, allowing you to attach standard CO2 tubing directly to the connector without extra fittings. Just slide your tubing over the barb and secure it with a hose clamp for a tight, pressure-proof seal. It’s an ideal solution for brewers looking for a straightforward setup with minimal hardware.
By eliminating the need for threaded connections, the barbed fitting offers a clean, streamlined solution for both fixed installations and mobile setups. It’s particularly useful for brewers who prefer a durable, tamper-resistant connection that won’t loosen during operation.
Quick Ball Lock Compatibility
Designed to snap onto the CO2 (gas) post of a standard Cornelius keg—also known as a Corny keg—this connector uses a classic ball lock mechanism for fast, reliable attachment. Simply press it into place, and you’ll hear a reassuring click that confirms a secure lock. When it's time to switch kegs or clean your system, a simple pull on the collar releases the fitting just as easily.
The ball lock system is trusted by homebrewers worldwide for its consistent sealing and compatibility across most kegging setups. It ensures your CO2 delivery stays steady and uninterrupted, which is key to keeping beer carbonated and flowing.
Strong, Long-Lasting Build
This connector is built from high-quality, food-grade plastic with stainless-steel internal components that are made to last. It resists pressure, physical wear, and harsh sanitising agents, making it perfect for repeated use in demanding homebrew environments.
Whether you’re using peracetic acid, Star San, or PBW, this connector will hold up through cleaning and reassembly without losing performance. Its rugged design ensures long service life, even in heavily used setups.
Compatible with Cornelius and Corny Kegs
Whether you're a traditionalist using Cornelius kegs or refer to them as Corny kegs, this connector is fully compatible with both. It fits all standard gas posts on these keg types and pairs easily with 1/4″ CO2 tubing—commonly used in homebrew draft systems.
It’s also compatible with most homebrew CO2 regulators, manifolds, and distribution systems, allowing for flexible integration into any setup. From basic single-keg systems to advanced multi-keg arrangements, this connector gets the job done reliably.
Perfect for Kegerators and Mobile Setups
The 1/4″ barb is especially suited for brewers building semi-permanent or mobile systems. Once clamped in place, the CO2 tubing remains secure—reducing the risk of disconnections during transport or operation.
If you’re setting up a kegerator, keezer, mobile tap unit or attending beer events, this connector provides a worry-free solution with fast installation and no extra fittings.
