Sera Suction Cups 16 mm – aquarium mounting accessories, pack for tubing and fixtures

Sera 16 mm suction cups are compact mounting accessories designed to secure tubing, air lines, heaters and small fixtures to glass or other smooth surfaces inside aquariums, terrariums and similar setups. Each cup features a 16 mm diameter contact area that provides a stable hold for lightweight hoses and components, helping to keep equipment organized and positioned without drilling or adhesives. The design supports routine aquarium maintenance and straightforward hobbyist installation.

Advantages

The suction cups offer a non-invasive mounting solution that preserves glass integrity and allows repositioning as needed. Their small size makes them suitable for tight spaces and unobtrusive placement behind plants or décor. Made from flexible material, the cups form a secure seal on smooth surfaces and are compatible with standard aquarium tubing and thin air lines. They are low-cost, simple to attach and remove, and reduce the risk of cable or hose strain on connected equipment.

Suitable for

• Securing aquarium tubing and airline hoses to glass walls
• Holding small heaters, thermometers or sensor leads in place
• Organizing air pumps and filter lines in terrariums and paludariums
• Temporary mounting of lightweight fixtures during maintenance

Key specifications

• Contact diameter: 16 mm
• Material: flexible elastomer/plastic (suitable for wet environments)
• Intended surface: smooth glass and similar non-porous surfaces
• Compatibility: designed for lightweight tubing, airline hoses and thin cables
• Colour: transparent or neutral to minimize visual impact

How to use

Clean the glass or smooth surface thoroughly to remove algae, dust or residues. Moisten the suction cup slightly with water to improve adhesion, press it firmly against the surface until the cup seats and creates a vacuum seal, then route the tubing or cable into the cup's holding area. To reposition, gently peel one edge of the cup to break the seal and move to the new location; clean both surfaces before reattaching for best results. For prolonged use, periodically check the seal and reposition if adhesion weakens.

Usage recommendations

Use these suction cups only on clean, non-porous surfaces and avoid mounting heavy equipment; they are intended for lightweight hoses and small fixtures. In aquatic environments, inspect attachments regularly to ensure secure hold and prevent strain on tubing connections. Store spare cups away from direct sunlight and high temperatures to preserve material flexibility.
