Metal adapter with non-return valve for KeyKeg DSI coupler

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.

Key benefits

  • Integrated non-return valve: blocks fluid backflow and helps maintain system stability.
  • Greater hygiene: reduces the risk of the drink flowing back into the circuit.
  • Equipment protection: helps prevent breakdowns and incorrect readings in regulators and accessories.
  • Robust construction: ideal for intensive use and frequent keg changes.
  • Simple installation: easily integrates into setups compatible with KeyKeg DSI coupler.

Compatibility

Compatible with KeyKeg DSI coupler (adapter for KeyKeg dispensing systems). Recommended for installations where you want extra protection against backflow and improved service stability.

Installation and maintenance

Do not force the threading and use the appropriate sealing method according to the type of joint (gasket/thread) in your setup. For maintenance, it is recommended to periodically check the cleanliness of the circuit and replace gaskets if they show wear.

Ideal for: hospitality, events, taprooms and any installation with KeyKeg DSI where maximum safety, hygiene and consistency in dispensing are required.
