The box holds one roll of tubing, 4 air stones, 4 red clear return valves, 4 control valves, 12 connectors and 12 suction cups.

• 25 ft of clear, flexible airline tubing with a 3/16 inch (4 mm) inner diameter
• 4 air stones
• 4 red clear return valves
• 4 control valves
• 12 connectors
• 12 suction cups

What the 25 ft roll and the fittings cover

The tubing runs 25 ft in a single length, which sets how far the air stones can sit from the pump. The 12 connectors join sections of tubing, and the 12 suction cups give the line points to be fixed against a surface.

The four return valves are red and clear, and they stop water from siphoning back through the line. Each of the four control valves adjusts the air output going to the tank, so a single pump can feed several outlets at different settings. The four air stones can be driven by air pumps.

Checks before you buy this kit

The tubing has a 3/16 inch (4 mm) inner diameter, so check that diameter against the outlet on your pump and against any fittings you plan to reuse. The manufacturer states the tubing fits most air pumps; a pump with a different outlet size is not covered by that description.

Measure the run you need before ordering. One roll of 25 ft is the only tubing in the kit, so a longer route from pump to tank needs more than this pack holds. The pack contains four return valves, four control valves, four air stones, twelve connectors and twelve suction cups, so check the count against the number of outlets you plan to run.

Do the air stones work with any air pump?

The manufacturer states that air pumps can drive the air stones in this kit. The tubing that connects them has a 3/16 inch (4 mm) inner diameter and fits most air pumps.

What size is the airline tubing?

The airline tubing measures 3/16 inch (4 mm) across the inside and comes as a 25 ft length.

How many return valves are in the pack?

The kit includes 4 return valves, each red and clear, and they stop water from back siphoning.

What does the adjusting valve do?

The kit has 4 control valves, and each one changes the air output for the fish tank.

How the parts work together

The clear, flexible tubing carries air from the pump, and its 3/16 inch (4 mm) inner diameter is the size that fits most air pumps. A red clear return valve sits in the line to stop water from back siphoning toward the pump.

Each control valve changes the air output for the fish tank, so the four of them let one pump feed several points at different settings. The twelve connectors link tubing runs and the twelve suction cups hold the line in place; the four air stones sit at the outlets and can be driven by air pumps.
