Airline Metal Control Taps

Airline Metal Control Taps

DARO Airline Metal Control Taps are metal airflow control valves for airline tubing. They give you precise control over the air flowing through your aquarium or hydroponic system. They suit South African fishkeepers and hydroponic growers who want to fine-tune their air supply with a durable fitting that lasts.

An air pump on its own delivers whatever output it is built for, which may be more or less than your setup needs. Fitting a DARO metal control tap inline lets you set the airflow at exactly the level you want. Your air stones, sponge filters, bubble ornaments or hydroponic aeration then get the right amount of air for optimal performance.

Key Benefits

• Precise airflow control: a precise control knob lets you adjust the airflow easily to your desired level, from a gentle trickle to a stronger stream.
• Durable metal construction: crafted from durable, long-lasting metal and built for reliable performance over time.
• Built for demanding use: the metal body handles the high pressures and constant, around-the-clock use typical of aquarium and hydroponic air systems.
• Corrosion-resistant: resists corrosion, rust and wear, which helps in humid fish rooms, grow tents and coastal homes.
• Low maintenance: its resistance to corrosion, rust and wear makes it a low-maintenance solution for your air control needs.
• Compact, sleek design: fits neatly into any setup without taking up much space, whether behind a cabinet, along a stand or beside a hydroponic reservoir.
• Quick, easy installation: simply connect it to your airline tubing and you are ready to go.

How to Use

• Cut your airline tubing at the point where you want to control the airflow.
• Connect the tubing to the control tap, which is compatible with 4 mm (5/32") airline tubing.
• Switch on your air pump.
• Turn the control knob to raise or lower the airflow until your air stone, filter or hydroponic aerator receives the amount of air you want.
• Re-adjust the knob whenever your setup changes, for example when you add livestock, move plants or change the air stone.
