## Long description

Sera suction cups 12 mm are small flexible mounts designed to secure tubing, air lines, heaters and other lightweight aquarium components to glass or other smooth surfaces. With a 12 mm diameter and pliable material, these suction cups allow easy attachment, repositioning and temporary fixing of accessories without drilling or adhesives, helping maintain a tidy layout in freshwater or marine setups.
Advantages
The 12 mm size provides a compact and discreet fixing point suitable for narrow tubing and fine parts. Flexible material offers reliable suction on clean, smooth surfaces and enables repeated removal and reattachment. Installation does not require tools, which preserves aquarium glass and reduces the need for permanent fixtures. The simple design is low-maintenance and can be inspected or moved as equipment changes.
Suitable for
 Securing small-diameter tubing and airline hoses
 Fixing lightweight heaters, sensors or probes
 Mounting small decorative or functional parts on glass panels
 Organising cables and feed lines inside the aquarium hood or sump
Key specifications
 Diameter: 12 mm
 Material: flexible suction-grade elastomer (soft PVC or similar)
 Surface compatibility: smooth glass, glazed ceramics, plastic panels
 Mounting type: push-fit suction cup for temporary attachment
 Colour: transparent or neutral tone to remain discreet
How to use
Ensure the target surface is clean, dry and free of algae, dust or mineral deposits for optimal adhesion. Press the suction cup firmly against the glass or panel until a secure seal forms; attach the tubing or part into the centre or to the integrated hub if present. To reposition, gently lift an edge of the cup to break the seal, then wipe the surface and cup and reapply. Regular inspection will confirm continued adhesion and alignment of secured items.
Usage recommendations
For best results, use on smooth, non-porous surfaces and avoid mounting heavy objects beyond the suction cup's capacity. Periodically clean both the suction face and the contact area on the aquarium glass. In applications with continuous heat or strong currents, check the hold more frequently and consider multiple cups or alternative mounting solutions for critical equipment.
