## Long description

ESSELTE Aqua Natura connector for air tube is a white polypropylene (PP) fitting designed to join flexible air tubing with different diameters. It connects 8 mm and 4 mm air tubes through six parallel passages, enabling multiple air lines in a compact single component. Supplied in a pack of 25 pieces, the connector is intended for pneumatic or aquarium air systems where a simple, mechanical transition between tube sizes is required.
Advantages
The connector is made of corrosion-resistant polypropylene, providing chemical stability and suitability for humid environments. Its six-passage layout allows multiple air feeds from one compact fitting, reducing the number of separate connectors needed. Its push-fit geometry enables quick assembly without special tools and helps maintain a reliable mechanical seal for standard flexible tubing. The white finish offers neutral appearance that blends with typical aquarium or equipment setups.
Suitable for
 Joining 8 mm to 4 mm flexible air tubing in aquarium systems
 Small pneumatic setups and hobby pneumatic projects
 Distributing air to multiple outputs from one supply line
 Temporary or semi-permanent installations where simple mechanical fittings are preferred
Key specifications
 Material: polypropylene (PP)
 Color: white
 Connections: six parallel passages for tubing
 Compatible tube diameters: 8 mm and 4 mm flexible air tubing
 Pack quantity: 25 pieces
How to use
Ensure tubing ends are clean and cut square for best fit. Insert the 8 mm and 4 mm flexible air tubes firmly into the respective passages until they reach a snug stop; the push-fit design secures the tubing mechanically. For aquarium applications, position the connector outside the tank or in a dry compartment where possible to minimize prolonged water exposure. Inspect connections after installation and apply gentle tension to confirm the mechanical grip; if necessary, use a small hose clamp for added security in higher-pressure or vibration-prone environments.
Usage recommendations
Use the connector within the pressure and temperature limits of standard flexible air tubing; avoid exposure to aggressive chemicals or prolonged direct sunlight. For critical pneumatic systems, verify compatibility of tubing and fitting materials and consider mechanical clamps or adhesive where a permanent, leak-free connection is required.
