Aquarium Suction Cup DeWalt TN-44825, black, 34×20 mm, rectangular holder 11 mm, pack 50

DeWalt aquarium suction cups model TN-44825 are black rubber mounting elements sized 34×20 mm with an integrated rectangular holder 11 mm long. Supplied as a pack of 50, these suction cups are intended for temporary, removable fixation of tubing, small fittings, decorative elements or heaters to smooth surfaces such as aquarium glass. The soft rubber body provides a gentle grip without permanent adhesives, allowing repositioning and maintenance access while keeping components in place inside freshwater or indoor aquaria.

Advantages

These suction cups combine a compact footprint with moderate holding power on clean, non-porous surfaces. The rectangular 11 mm holder accepts straps, clip-on fittings or narrow tubing connectors, enabling versatile mounting options. As reusable rubber mounts they avoid drilling or adhesive residues and can be removed and repositioned without damaging glass or equipment. Supplied in a 50-piece pack, they are suitable for multi-point fixation or for servicing several tanks.

Suitable for

• Securing airline tubing and small hoses inside aquaria
• Mounting small filters, heaters or temperature sensors to aquarium walls
• Fixing decorative elements or lightweight fittings to glass or smooth acrylic
• Temporary organization of cables and cords near aquaria

How to use

Before mounting, clean the glass or acrylic surface and the suction cup face to remove dust, grease or residues. Moisten the suction cup slightly with water to improve sealing, press firmly against the smooth surface until the cup adheres, and route tubing or attach the accessory into the rectangular holder. For secure positioning use multiple suction cups along the tubing or larger items. To remove, lift the edge of the rubber cup to break the seal and peel away gently; clean both surfaces after removal.

Usage recommendations

For reliable holding, attach only to flat, clean, non-porous surfaces and avoid use on textured glass. Regularly inspect suction cups for wear or hardening of the rubber and replace if adherence weakens. Do not rely on suction cups as the sole support for heavy equipment—use additional mechanical mounting where necessary.
