Material and durability: Made from rust-resistant steel for long-lasting use. The sturdy construction withstands repeated cleaning without bending or corroding. Design that cleans thoroughly: Double-sided, curved tube-cleaner shape reaches inside bends and tight areas. The curved profile and flexible shaft provide consistent contact with the tube wall to remove algae, dirt, and deposits. Two brushes in one set: Includes two different brushes to cover a range of tube and hose diameters. Having both brushes makes routine maintenance faster and more effective. What it removes: Effectively scrubs away algae, biofilm, sediment, and other buildups that reduce flow and contaminate systems. Where it works: Designed for aquariums and laboratory environments, and suitable for any application where small-diameter tubing, hoses, or narrow glassware must be kept clean. Performance and ease of use: Flexible shaft and curved heads allow access to hard-to-reach spots without excessive force. Simple to use for quick spot cleaning or regular maintenance. Use scenarios Aquarium maintenance: Clean filter hoses, air lines, heater sleeves, and other aquarium tubing to restore water flow and limit algae growth. Laboratory equipment: Remove deposits from glass tubing, narrow connectors, and transfer lines to maintain experiment accuracy and prevent contamination. Routine system upkeep: Ideal for periodic cleaning of tubing in filtration systems and small pumps where deposits can reduce performance. What you get A pair of steel, rust-resistant tube brushes with double-sided, curved heads and flexible shafts to tackle stubborn grime in tight spaces. Why you need it Prevents clogging and contamination by removing build-up before it causes problems, saves time with a two-brush set, and delivers reliable, durable cleaning performance for aquarium and lab applications.
