Suction Cups for Aquarium PartyDeco TN-44881, black, 23×30 mm, pack of 50

PartyDeco suction cups TN-44881 are compact black rubber/silicone mounting cups sized 23×30 mm supplied in a pack of 50. Designed for aquarium use, these suction cups provide a discrete and reusable method to fix decorations, tubing, heaters or air lines to the inside surface of glass or smooth acrylic panels. The soft material and the curved cup profile create a reliable seal on clean, flat surfaces while allowing easy repositioning without tools.

Advantages

The black rubber/silicone construction resists slipping and limits visual impact inside the tank. At 23×30 mm each cup is small enough for tight placements yet large enough to hold light-to-moderate loads typical of aquarium tubing, air stones and lightweight decorations. Supplied as a pack of 50, the set is convenient for outfitting multiple fixtures or for replacing worn cups over time. The flexible material works with both freshwater and saltwater environments when used on appropriate surfaces.

Suitable for

• Fixing airline tubing, heater cables and small power cords to aquarium walls
• Attaching lightweight ornaments, background elements or plants to glass or acrylic
• Securing air stones, CO2 lines and drip systems in place
• Temporary mounting tasks where non-permanent, tool-free attachment is needed

When it may not be suitable

These suction cups are intended for light-to-moderate loads; they are not engineered to support heavy ornaments, large heaters, or equipment that exerts strong downward or outward force. Performance depends on a clean, flat, non-porous surface—textured or curved surfaces will reduce holding power. In high-flow areas or where frequent temperature changes occur, check adhesion regularly.

Key specifications

• Material: rubber/silicone blend
• Colour: black
• Dimensions (approx.): 23 × 30 mm
• Pack contents: 50 suction cups
• Intended environment: freshwater and saltwater aquariums

How to use

Ensure the glass or acrylic surface is clean and free of algae, oils or residue before applying. Moisten the inside of the cup slightly if needed, press firmly against the flat surface to expel air and create a seal, then insert the tubing or hang the lightweight item from the cup’s lip or attachment point. To reposition, gently lift an edge to break the seal and move to the new location, then reapply pressure to restore adhesion. Inspect periodically and replace any cups that lose elasticity or fail to hold securely.

What to consider before purchase

• Verify that the 23×30 mm dimensions suit your tubing, cords or decorative elements
• Confirm tank surfaces are flat, smooth and clean for reliable adhesion
• Assess the weight and force of items to be mounted—use alternative hardware for heavy loads
• Consider that saltwater environments may require more frequent inspection due to deposits

Usage recommendations

For best results, clean the surface with a non-oily, aquarium-safe cleaner and dry before application. Use several suction cups to distribute load and reduce stress on individual cups. Regularly check adhesion, especially after refilling or maintenance, and replace cups showing deformation or loss of suction.
