This 8 mm (5/16) Duotight 4-way manifold makes it easy to split one gas line into four controlled outputs. Each outlet includes an isolation valve so you can shut off a single line without touching the rest of the system, plus an integrated check valve to help stop backflow. It is a clean way to run multiple kegs, multiple fermenters, or a mix of both from a single regulator.

Push-fit Duotight connections keep the install simple. Cut your 8 mm EVABarrier or compatible tubing square, push it in fully, and you are set. When it is time to reconfigure, the tubing releases without fighting clamps or barbs.
