## Long description

Sera suction cups 18 mm, pack of 2 are compact rubber mounting accessories designed to attach tubing, air lines, cables or lightweight fittings to aquarium glass and other smooth surfaces. Each suction cup has an 18 mm diameter and a central recess that holds small hoses or clips, providing discreet, stable support for filters, heaters, airline tubing and decorative elements. Supplied as a pair, these suction cups allow flexible positioning and a spare for replacement.
Advantages
These 18 mm suction cups are made from soft rubber that conforms to glass to create a reliable vacuum contact and reduce the chance of accidental detachment. Their small size keeps tubing and accessories tidy and minimally visible inside the aquarium. The pack of two provides options for symmetric or distributed mounting and makes it easy to replace a worn or lost suction cup without disrupting the whole setup.
Suitable for
 Securing airline tubing for air pumps and diffusers
 Holding small filter or heater tubing close to the aquarium wall
 Fixing light cables or sensor wires along glass panes
 Attaching lightweight decorative elements or guide clips
Key specifications
 Material: soft rubber (elastic, water-resistant)
 Diameter: 18 mm
 Quantity: 2 pieces per pack
 Compatibility: suitable for smooth, non-porous surfaces such as glass or glazed acrylic
 Design: central recess for small tubing or clip attachment
How to use
Clean the glass or smooth surface to remove algae, dust and mineral deposits before applying the suction cup. Press the cup firmly against the surface to expel air and form a tight seal. Insert the tubing, cable or clip into the suction cup’s central recess and adjust orientation as needed. For heavy or tensioned lines, use multiple suction cups to distribute load and check adhesion periodically for safety.
Usage recommendations
For best performance, avoid placing the suction cups on textured or porous surfaces. Replace suction cups that show signs of hardening, cracking or permanent deformation. When routing tubing for filters, heaters or air pumps, allow slight slack to prevent strain on fittings and regularly inspect attachment points during routine aquarium maintenance.
