A 4-way Duotight gas manifold with 8mm (5/16″) push-fit connections, complete with integrated check valves and individual isolation valves. Designed to distribute CO₂ to multiple kegs with control and backflow protection.

This Duotight 4 Way Manifold allows you to split a single regulated gas supply into four independent outlets. Each outlet features its own isolation valve and internal check valve, giving you control over individual kegs while preventing gas or liquid from flowing back into the system.

Ideal for kegerator and keezer builds running multiple kegs from one regulator using 8mm EVABarrier or compatible tubing.

Key Features & Benefits

• 4 x 8mm (5/16″) Duotight push-fit outlets — fast, secure gas connections

• Integrated check valves — prevents backflow between kegs

• Individual isolation valves — shut off gas to each keg independently

• Single gas inlet — distribute one regulator supply to four lines

• Compact, tidy layout — ideal for fridge or collar mounting

• Designed for modern draft systems — compatible with EVABarrier tubing

Applications / Compatibility

• Designed for 8mm (5/16″) OD tubing

• Compatible with Duotight push-fit fittings and EVABarrier gas line

• Suitable for:

  • Multi-keg kegerator setups

  • Keezer collar gas distribution

  • CO₂ supply splitting from a single regulator

• Not compatible with 6mm or 3/8″ tubing without appropriate adapters. A Duotight – 8mm (5/16″) Plug can be used to cap either end.

Installation Notes

Cut tubing square and insert fully into each Duotight port to ensure a proper seal. Mount the manifold securely to prevent movement and strain on fittings. Pressure test the system after installation before use.

Care / Maintenance Notes

Periodically check for leaks and ensure isolation valves operate smoothly. Keep gas lines clean and free from contamination to maintain performance.

Use this gas manifold as part of your kegerator build – check out this video from our YouTube channel showing how to do this with other Kegland products.
