Duotight Inline Ball Valve for EVABarrier Tubing – 8mm & 9.5mm

Duotight Inline Ball Valves for Quick, Leak-Free Shutoff

Upgrade your draft system with Duotight Push-In Ball Valves, available in both 8 mm (5/16") and 9.5 mm (3/8") sizes for EVABarrier tubing. These inline shutoff valves give you precise control over gas and beverage lines with a simple quarter-turn—perfect for kegerators, keezers, jockey boxes, manifolds, and homebrew draft systems.

Designed for EVABarrier Tubing

• 8 mm (5/16") Version: Ideal for 8 mm OD EVABarrier draft line, including 4 mm ID x 8 mm OD and 5 mm ID x 8 mm OD tubing. Great for serving beer, seltzer, and other beverages where you want precise restriction and smooth flow.
• 9.5 mm (3/8") Version: Perfect for 9.5 mm OD EVABarrier tubing, commonly used for higher-flow beverage lines and gas runs. A great match for larger systems, trunk lines, or setups with inline regulators and flow-control hardware.

Reliable Push-In Performance

• Push-to-Connect Convenience: Simply cut your EVABarrier line square, push the tubing into the fitting, and you’re locked in—no hose clamps or barbed fittings required.
• Quick Release: To disconnect, press the collet in and pull the line out. Swapping components or reworking your draft routing takes seconds.
• Superior Seal: Double EPDM O-rings deliver a tight, reliable seal that resists leaks even when tubing bends around corners or runs through cramped spaces.
• Draft-System Ready: Suitable for both gas (CO₂, nitrogen blends) and beverage lines, making these valves extremely versatile in home and small commercial setups.

Built for Draft System Durability

• Robust Construction: Food-grade acetal plastic body with stainless steel locking teeth for long-term reliability and repeated connections.
• High Pressure Rating: Rated up to 150 psi for use with pressurized draft systems.
• Temperature Rating: Rated up to 212°F (100°C), so they can tolerate hot cleaning solutions and warm environments when needed.

Applications in Your Homebrew Setup

• Inline Shutoff: Install on gas or beverage lines to isolate individual kegs, manifolds, or sections of your draft system.
• Cleaning & Maintenance: Quickly shut off sections of line when cleaning, swapping kegs, changing regulators, or troubleshooting.
• System Expansion: Perfect for modular systems using EVABarrier tubing and Duotight fittings—add more valves as your draft setup grows.

Important Usage Note

• Do Not Use with Chlorine: Avoid bleach and chlorinated cleaners, as they can damage both the plastic body and stainless steel components. Use brewery-safe cleaners and sanitizers instead.
