4-Way Duotight Gas Manifold with Check Valves — 8mm Push-In Tubing

Upgrade Your Draft Setup with the Duotight 4-Way Gas Manifold The Duotight 4-Way Gas Manifold offers a modern, high-performance alternative to traditional heavy brass or aluminum manifolds. Built for the homebrewer who demands reliability and ease of use, this manifold allows you to split a single CO2 or Nitrogen line into two separate outlets with independent shut-off control.

• Leak-Proof Double O-Ring Technology: The secret to the Duotight system is the high-quality EPDM double O-ring design. Unlike standard push-in fittings, Duotight uses two sealing surfaces to provide twice the protection against leaks. This design also allows for a tighter bend radius in your tubing without breaking the seal, making it perfect for tight spaces inside a kegerator.
• Integrated & Removable Check Valves: Protect your expensive CO2 regulator from accidental beer backflow. Each outlet features an integrated check valve that ensures gas only flows one way. For advanced users who require bi-directional flow, the check valves can be easily removed by popping the black retainer tabs with a flat-head screwdriver.
• Modular & Expandable Design: Your draft system is always growing, and your manifold should too. The Duotight 4-Way Manifold is fully modular. You can connect multiple units together using 8mm rigid joiners or cap the end with an 8mm plug to create a custom configuration.

Please Note: The Duotight Manifolds feature 8mm Duotight connections at both ends. One end is intended for your gas line and the other can be used to attach another manifold or a variety of accessories. If you will not be installing anything on the other end, you will need a Duotight 8mm Plug to cap the opposite end from your Gas In (see below).

Mounting Solutions

Every manifold comes ready for installation with button-head screws for standard mounting. If you prefer not to drill into your kegerator or fermentation chamber, we suggest using Duotight Adhesive Brackets (DUO263) for a secure, tool-free setup.
