Suction cup for aquarium ZOLUX 30×15 mm, hole Ø 7 mm, with hook, pack 50

Transparent suction cups from ZOLUX sized 30×15 mm with a central hole of 7 mm and an integrated hook. Supplied as a pack of 50 pieces, these suction cups are designed for attaching pipes, heaters, air tubing and lightweight décor to aquarium glass or acrylic. The compact shape and clear material make them unobtrusive inside freshwater and saltwater environments while offering removable, non-permanent fixing without tools.

Advantages

The suction cups provide a reliable temporary mounting solution that is easy to reposition. The central 7 mm hole accepts standard tubing and small fittings, while the integrated hook adds extra support for wires or lightweight accessories. Made from transparent material, they minimize visual impact in the aquarium and resist common aquarium conditions encountered in both freshwater and marine setups.

Suitable for

• Securing air tubing and airline connectors

• Fixing return pipes and filtration tubing
• Attaching lightweight decorations and background elements
• Temporary cable or filament routing along aquarium walls

How to use

Clean and dry the glass or acrylic surface where the suction cup will be applied to ensure full contact. Press the suction cup firmly against the surface to expel air and create suction; if needed moisten the cup slightly for improved seal on perfectly smooth surfaces. Insert tubing, pipe or cable through the 7 mm central hole and hang lightweight items on the integrated hook. To reposition or remove, gently lift the edge of the suction cup to release the seal and reapply as required.

Usage recommendations

Inspect suction cups periodically for wear or loss of elasticity, especially in heated or saltwater environments. Avoid using them to support heavy loads or critical equipment; use dedicated clamps or brackets for heavier devices. For long-term reliability, clean both cup and surface regularly to prevent biofilm and mineral buildup that can reduce suction performance.
