Suction Cup for Aquarium Fixi 5×26 mm, black, pack of 50

Fixi black suction cups, size 5×26 mm, come in a pack of 50 and are made for attaching tubing, ornaments, heaters and cables to smooth aquarium glass and acrylic surfaces. Their compact 5×26 mm profile provides discreet mounting for small to medium aquarium fittings where minimal visual impact is required. These suction cups are suitable for organizing equipment, securing decorations and routing airline or heater cords without drilling or adhesives.

Advantages

The suction cups offer a simple, non-invasive attachment method that preserves the aquarium structure and finishes. Their black color blends with dark tubing and many aquarium backgrounds, reducing visibility of mounts. The cup profile is sized for firm hold on clean, flat surfaces and allows repositioning when necessary. Supplied in a pack of 50, they provide enough units for multiple mounting points or spare replacements.

Suitable for

• Mounting airline tubing and small-diameter heater cables
• Securing lightweight ornaments and decorations
• Organizing cords and power leads along aquarium walls
• Temporary or adjustable placement of sensors and small accessories

Key specifications

• Material: flexible plastic (suction cup body)
• Color: black
• Dimensions: 5 mm (diameter) × 26 mm (stem/overall length)
• Pack quantity: 50 pieces
• Surface compatibility: smooth glass and acrylic

How to use

Ensure the glass or acrylic surface is clean and free of algae, dust or silicone residue for best adhesion. Moisten the suction cup slightly before applying to enhance the vacuum seal, then press firmly against the surface to expel air. Insert the tubing, cable or small accessory into the cup stem or slot as appropriate. To reposition, peel the edge of the cup to break the seal, clean the surface if necessary, and reapply.

Usage recommendations

For reliable hold, avoid applying suction cups to curved, frosted or textured surfaces. Check attachment points periodically and replace any cups that show deformation or reduced sealing capability. Use multiple cups for longer runs of tubing or heavier decorations to distribute load and reduce stress on individual mounts.
