Protect your installation and ensure stable service. This metal adapter with non-return valve prevents beer or gas/air from flowing back from the coupler into the line, keeping the system cleaner, safer and more consistent with every pour.
The metal adapter with non-return valve for KeyKeg DSI coupler is an accessory designed to improve dispensing reliability in KeyKeg systems. Its main function is to prevent reverse flow from reaching the gas regulator or air compressor, as well as to avoid cross-contamination and help protect sensitive components such as regulators, gauges and lines.
Built in high-strength metal (quality finish), it is designed for intensive use in hospitality and for setups where maximum hygiene and operational safety are required. Its compact format makes line installation easier and reduces critical points where dirt can accumulate.
