For Oxygen Pumps Only: Great one-way check valve for most common aquarium air pumps. NOT suitable for CO2 or other high-pressure systems to avoid crack and leak.
Small & Light: Size: 2.1″ L x 0.55″ W; Diameter of air holes: 0.12″; Weight: 0.1 oz. Standard ID airline tubing: 3/16″. Add little weight to your hose for smooth airflow.
Ideal Pump Protectors: Prevent backflow of water through the tubing during a power outage or pump pause. Essential accessories for basic aeration setup in your fish tanks.
Sturdy & Quiet: Made of reliable plastic which can be tightly connected to the hose without air leak. Durable to endure long-time use without making noise.
Easy Maintenance: Clean the valve regularly. Please poke it with a slim stick from the inlet side to push it open when it gets clogged inside and restricts air flow.
