Suction Cup for Aquarium Aliga 13×30 mm, transparent, pack of 50

Transparent suction cup by Aliga, size 13×30 mm, supplied in a pack of 50 pieces. Designed to secure tubing, air lines, small decorations and accessories to glass surfaces in aquariums. The soft, flexible material allows easy attachment and repositioning on smooth surfaces and is suitable for both freshwater and marine setups where a reliable temporary fixation is needed.

Advantages

The suction cup offers a compact footprint with strong holding power relative to its size, enabling neat routing of air lines and tubing along aquarium walls. Its transparent finish minimizes visual impact inside the tank. Supplied in a bulk pack of 50, it provides multiple mounting points for medium and larger systems or for repetitive tasks over time. The flexible rim forms a reliable seal on flat glass and smooth acrylic surfaces, while the molded eyelet or groove secures tubing without the need for adhesive or clamps.

Suitable for

• Fixing airline tubing and small low-flow hoses to aquarium glass
• Mounting lightweight decorations, thermometers or small sensors
• Temporary attachment of LED cables or filter overflow tubing
• Organizing hoses and cables behind or inside aquaria in both freshwater and marine tanks

Key specifications

• Material: flexible transparent elastomer suitable for contact with aquarium environments
• Dimensions: approximately 13 mm (inner/attachment width) × 30 mm (cup diameter)
• Pack quantity: 50 identical suction cups
• Mounting surface: flat, smooth glass or acrylic recommended

How to use

Clean the mounting surface thoroughly to remove algae, dust or residues and dry it. Moisten the suction cup slightly with clean water to improve the initial seal, then press firmly against the glass or acrylic until the rim lies flat and an audible click or firm hold is felt. Thread the airline or cable into the molded eyelet or groove; ensure the tubing sits securely without excessive bending. To reposition, gently lift at the edge of the rim to release the seal, clean the surface again if necessary, and reapply.

Usage recommendations

For best performance, install suction cups on clean, smooth sections of glass and avoid textured or curved areas. Replace any suction cup that shows permanent deformation or becomes brittle. Periodic inspection ensures tubing remains secure and prevents strain on connectors and fixtures.
