Airline control Valves - 50 pack

Adjust airflow to your aquarium's air-powered accessories with airline control valves. These fittings let you regulate the air passing through compatible tubing, helping you fine-tune bubbling and balance airflow in a branched airline setup.

• Pack contains 50 airline control valves
• Adjusts airflow through compatible aquarium airline tubing
• Useful for managing airflow to air stones and other air-powered accessories

Check the valve connections against your tubing before purchasing. Make adjustments gradually and follow your air pump manufacturer's guidance on airflow restriction. A control valve is not a non-return valve and does not provide backflow protection.
