## Long description

Flexible aquarium hose aqua nova 16/21 mm — 1 m is a transparent, bendable tubing designed for water circulation and plumbing in aquaria and small water systems. With a 16 mm inner diameter and 21 mm outer diameter, this 1 m length hose fits pumps, filters and fittings that accept these standard dimensions. The hose is intended for connections where a flexible, reliable conduit for water is required during routine maintenance, equipment setup or temporary installations.
Advantages
The tubing offers flexibility that simplifies routing around obstacles inside cabinets and within aquarium stands while maintaining a smooth bore for steady water flow. Made for repeated handling, the hose resists kinking under normal installation angles and provides secure fitment on barbed connectors and push-fit fittings sized for 16/21 mm. Its transparency helps monitor water flow and spot air pockets or debris without disassembly.
Suitable for
 Connecting aquarium pumps to canister filters or external filters
 Linking return lines for sump systems in small and medium aquaria
 Temporary or permanent plumbing of seasonal or auxiliary water devices
 Drainage during water changes and maintenance tasks
Key specifications
 Inner diameter: 16 mm
 Outer diameter: 21 mm
 Length: 1 m
 Material: flexible transparent tubing suitable for freshwater aquarium use
 Compatible with barbed and push-fit connectors sized for 16/21 mm tubing
How to use
Cut the hose to the required length with a sharp hobby knife or hose cutter for a clean, square end. Slide the tubing fully onto the barbed end of the connector or push-fit until it seats against the fitting shoulder; secure with a hose clamp if additional retention is needed. Route the hose to avoid sharp bends and compressive pinches; allow gentle radii to maintain flow and prevent stress on connectors. For temporary setups, use quick-disconnect fittings where appropriate to simplify removal during maintenance.
Usage recommendations
Inspect the hose periodically for signs of wear, discoloration or hardening and replace if deformation or leaks appear. Rinse new tubing before first use to remove any manufacturing residues. Use corrosion-resistant clamps in salty or chemically treated environments and avoid exposure to direct sunlight to extend service life.
