Aquarium Hose AQUA DELLA flexible on cardboard spool 9/12 mm × 3 m

AQUA DELLA flexible aquarium hose supplied on a cardboard spool, inner diameter 9 mm and outer diameter 12 mm, length 3 m. This PVC tubing is designed for water transfer and air lines in aquarium systems and related equipment. The hose is delivered wound on a compact spool for neat storage and easy unrolling, suitable for connecting filters, pumps, external devices and for routine maintenance tasks in home and small-scale aquarium setups.

Advantages

The hose combines bendable PVC construction with dimensional stability to maintain flow without kinking in typical aquarium applications. Its 9/12 mm diameters match common fittings used on small pumps and filter outlets, enabling straightforward connections. Supplied on a cardboard spool, the tubing stays organized and is protected from tangling and minor deformation during storage.

Suitable for

• Connecting aquarium filters and external canister filters
• Supply and return lines for small aquarium pumps
• Air lines for low-pressure aeration systems
• Draining and filling tanks during maintenance
• Temporary or semi-permanent plumbing in home aquaria

How to use

Select hose clamps or push-fit connectors that match the 9/12 mm dimensions and secure connections to pump or filter outlets. Cut the tubing cleanly with a sharp blade or hose cutter to the required length and slide fittings over the tubing end before tightening clamps to prevent leaks. When routing the hose within an aquarium stand or behind equipment, avoid sharp bends and compressions that could restrict flow; support long runs where needed to prevent sagging.

Usage recommendations

Before first use, flush the hose with clean water to remove any manufacturing residues. Inspect connections periodically for signs of wear or leaks and replace sections showing hardening, cracking or persistent deformation. For long-term installations, use appropriate clamps and connectors rated for aquarium use and avoid exposure to direct sunlight or heating elements that can accelerate material aging.
