Stainless G-Type Keg Coupler with 8mm duotight Push In Fitting

Upgrade your draft system with the ultimate combination of hygiene, durability, and convenience.

This G-Type (Grundy) Keg Coupler is engineered for serious brewers and bar owners who demand the best. Constructed with a 304 Stainless Steel body and probe, this coupler ensures that your beverage only touches sanitary metal, preventing metallic off-flavors and ensuring longevity even with acidic beverages like ciders or wines.

The standout feature of this unit is the Integrated 8mm (5/16") Duotight Push-Fit connections. Say goodbye to worm clamps and cut fingers. These fittings allow you to connect and disconnect your gas and beer lines in seconds while maintaining a superior double O-ring seal.

Key Features

• 100% Stainless Steel Contact Path: The liquid probe and body are made from high-grade 304 Stainless Steel. Unlike chrome-plated brass, this will not erode or taint the flavor of your beer over time.
• Tool-Free Connections: Features integrated 8mm Duotight fittings on both the Gas In and Liquid Out ports. Compatible with 8mm OD (5/16") EVABarrier tubing.
• G-System Compatibility: Fits standard triangular-lobed G-System keg valves (often referred to as the Grundy system).
• Integrated Pressure Relief Valve (PRV): Safety relief valve rated to release excess pressure (typically ~55-65 PSI). The ring-pull design allows you to manually vent head pressure easily.
• Gas Duckbill Valve: Prevents liquid from backflowing into your gas regulator, protecting your expensive CO2 equipment.
• Ergonomic Handle: Short, sturdy handle design ideally suited for tight spaces in kegerators or keezers.
