Aquarium tubing AQUA DELLA flexible hose on cardboard spool 4/6 mm, 100 m

AQUA DELLA flexible aquarium tubing supplied on a cardboard spool offers a continuous 100 m length of soft, bendable hose with a 4 mm inner diameter and 6 mm outer diameter. The product is intended for routing air lines, low-flow water connections and linking small pumps and filters in aquariums, terrariums and other hobby installations. The tubing is easy to cut to length and mount with standard aquarium fittings, and the cardboard spool keeps the hose organized during storage and installation.

Advantages

The flexible construction provides easy bending without kinking, allowing neat routing around rocks, plants and equipment. The consistent inner and outer diameters enable reliable connections with standard push-fit and clamp fittings used in aquarium and terrarium setups. Supplied on a cardboard spool, the hose is simple to dispense and measure, reducing waste and tangles during long installations or maintenance tasks.

• Air lines for airstones, air pumps and regulators

How to use

Measure the required run and cut the tubing cleanly with a sharp knife or scissors to ensure smooth, flat ends. Push the hose onto barbed fittings or push-fit connectors until it seats firmly; for added security use small hose clamps where appropriate. Route the tubing to avoid tight bends and kinks, and secure it along surfaces or equipment to prevent movement. Periodically inspect for stiffness, clouding or biofilm buildup and replace sections as needed to maintain flow and hygiene.

Usage recommendations

For air applications, confirm compatibility with the air pump’s outlet diameter before final installation. When used for water lines, avoid prolonged exposure to direct sunlight to reduce material aging. Store the cardboard spool in a dry place to prevent deformation and keep spare lengths for future adjustments.
