Non return valve

Add a one-way valve to your aquarium airline to help prevent water from flowing back towards the air pump when airflow stops. A non-return valve is a practical accessory for air-powered aquarium setups.

• Allows airflow towards the aquarium
• Helps reduce the risk of water backflow towards the pump
• Fits into a compatible airline setup

Install in the correct airflow direction, following the valve markings or supplied instructions. Check compatibility with your airline tubing and test airflow before use. Inspect regularly and follow your air pump manufacturer's installation guidance.
