8mm (5/16) duotight x 6 Way Manifold with Check Valves & Isolation Valves

8mm (5/16") duotight x 6 Way Manifold

The duotight 8mm (5/16") 6‑Way Manifold is the ultimate gas‑distribution upgrade for multi‑keg setups, giving you clean, modular control with built‑in check valves and isolation valves on every outlet. Each check valve can be removed when you want gas or filtered water to move freely in all directions, making this manifold adaptable to any brewing or dispensing layout.

Removing a valve is simple — use a thin flat‑head screwdriver to slide the black retainer tabs and pop the ball valve out. The manifold includes integrated mounting points for button‑head screws, and for kegerator installs we recommend pairing it with duotight 8mm adhesive brackets for a clean, drill‑free setup.

Built with Generation 2 duotight technology, this manifold delivers superior sealing performance thanks to its double O‑ring system, colour‑coded collets, and high‑performance Polyketone (POK) construction. With excellent chemical resistance, UV stability, and cold‑temperature performance, duotight fittings offer unmatched reliability across brewing and gas‑distribution systems.

The double O‑ring design also allows tighter hose bends without leaks — a common failure point in other push‑fit fittings. No clamps are required; simply cut your EVABarrier line straight, push it in, and enjoy a secure, gas‑tight seal.

(Not suitable for liquids other than filtered water.)

Thread Compatibility
This manifold’s threaded outlets suit:

• MFL Threaded Ball Lock Disconnects
• MFL Threaded Pin Lock Disconnects
• MK3 & MK4 Regulators
• Most homebrew fittings using MFL thread

Not compatible with MK5 Regulators.
