Why Good Airline Tubing Matters
Maintains consistent airflow to all air stones and diffusers
Prevents kinks, leaks, and back-pressure on pumps
Black tubing helps block light, reducing algae growth
Clear tubing makes it easy to trace runs and connections
Airline Tubing Sizes
4mm Airline Tubing
The standard size for most small-to-medium hydroponic air pumps. Flexible, compact, and compatible with common fittings.
8mm Airline Tubing
Wider bore for higher airflow pumps and long runs across larger systems. Ideal for multiple outlet manifolds and commercial-scale setups.
Types of Airline Tubing
Black Airline Tubing
Blocks light to reduce algae growth. Durable and discreet — great for keeping tanks tidy.
Clear Airline Tubing
Easy to trace air flow paths. Popular in aquarium setups but works for hydro too.
Silicone Airline Tubing
Soft, flexible, highly kink-resistant, even in cold conditions.
PVC Airline Tubing
Strong, cost-effective, and resistant to wear. Slightly firmer than silicone but great for long-term setups.

Airline Tubing FAQs
What size airline tubing do I need?
Most hobby setups use 4mm airline tubing. Large reservoirs or high-flow pumps may require 8mm tubing to reduce resistance.
What’s better: black or clear airline tubing?
Black tubing prevents light penetration, helping stop algae build-up. Clear tubing is easier to trace visually. Both perform the same function.
Silicone vs PVC airline tubing — what’s the difference?
Silicone is softer, more flexible, and highly kink-resistant. PVC is firmer, more durable, and often more affordable.
Can I use aquarium airline tubing for hydroponics?
Yes. Standard aquarium airline tubing works with hydroponic air pumps and stones. For larger systems, 8mm tubing is better for airflow.
