Aquarium airline tubing Tetra EX1500 plus by Tetra — flexible airline hose for air pump and accessories

Tetra EX1500 plus is a flexible aquarium airline tubing designed to provide a reliable, airtight conduit between air pumps and aeration accessories such as airstones, air-driven decorations and check valves. Made for common home aquariums, this hose accepts standard fittings and offers flexibility that simplifies routing around aquarium stands and filters while maintaining steady airflow to connected devices.

Advantages

The tubing is soft and pliable, making it easy to cut to length and to route in confined spaces without kinking. Its construction ensures consistent air delivery with minimal leakage at fittings and connections. Compatibility with standard aquarium accessories reduces the need for adapters, and the material resists cracking and hardening over time under normal aquarium conditions.

Suitable for

• Connecting external or internal air pumps to airstones and diffusers
• Linking check valves, bubble counters and air-driven ornaments
• Running air lines through cabinet openings and behind filters
• Temporary or permanent installations in freshwater home aquaria

Key specifications

• Flexible soft tubing suitable for aquarium aeration
• Compatible with standard air pump connectors and tubing fittings
• Cut-to-length design for custom installations
• Durable material resistant to cracking and hardening in typical aquarium environments

How to use

Measure the required length between the air pump and the aeration accessory, allowing extra length for routing. Cut the tubing cleanly with scissors or a sharp knife. Push one end firmly onto the pump outlet, and the other onto the accessory or fitting until it seats securely. If required, use hose clamps or tubing connectors to secure connections in high-pressure situations. Periodically inspect the tubing for signs of wear, brittleness or blockages and replace if airflow is reduced.

Usage recommendations

For reliable long-term performance, avoid prolonged direct exposure to strong sunlight and high heat, and keep the tubing clear of sharp objects. When installing multiple lines, label or color-code sections to simplify maintenance. Replace tubing that shows signs of discoloration, cracking or reduced flexibility to maintain consistent aeration.
