Duotight Push-In Fitting - 8mm OD Gas Manifold w/ Check Valves

• Dual O-Ring Sealing System: Built with premium EPDM double O-rings that double the sealing surface compared to standard push-in fittings, delivering maximum reliability and a completely leak-free gas system.
• Flexible Modular Design: Includes integrated check valves on every outlet to block backflow, with removable ball valves and a simple pop-tab mechanism for tool-free customization, swapping, or plugging individual lines.
• Quick Tool-Free Setup: Works with 8mm EVABarrier tubing for secure connections in seconds. Push-to-connect design requires no clamps and fits any kegerator or fermentation chamber with flexible mounting options.

Please Note: Duotight Manifolds have 8mm Duotight connections on both ends—one for your gas line, one for accessories or additional manifolds. If the second end remains unused, you will need an 8mm Plug to cap it.

The Duotight Gas Manifold simplifies draft systems with built-in check valves on every ball valve outlet to prevent backflow. These valves are easily removable if you need bidirectional gas flow. Available in 2-Way, 4-Way, and 6-Way configurations, all using 8mm push-to-connect inlets and outlets for instant EVABarrier tubing connections.

Modular & Customizable
Designed for maximum flexibility, this manifold lets you shut off or remove lines permanently using Duotight 8mm Plugs. Individual ball valves can be swapped or removed with a thin flat-head screwdriver to pop the black retainer tabs. Connect multiple manifolds using 8mm Rigid Joiners to expand capacity as needed.

Installation & Mounting
Comes pre-drilled with button-head screws for standard mounting. For damage-free installation on kegerators or fermentation chambers, use Duotight Adhesive Brackets for secure, tool-free fastening.

Superior Double O-Ring Performance:
Two high-quality EPDM O-rings provide twice the sealing surface of standard fittings, making them exceptionally reliable and resistant to leakage. This design also permits tighter tubing bends without compromising the seal—a common problem with single-ring alternatives.

EPDM material offers superior chemical resistance, excellent gas transmission rates, better wear resistance than silicone or vinyl, and is BPA-free for long-lasting performance.

No Clamps Required
Cut tubing straight with a sharp blade to ensure a complete seal. To disconnect, simply push the collet and slide the hose free. For precision cuts, a dedicated Tube Cutter with Duotight Removal Tool is recommended.
