Heater Suction Cup Holder Set (2-Pack)

The Heater Suction Cup Holder Set is a 2-pack of replacement mounting brackets designed to secure aquarium heaters to glass panels. Over time, factory suction cups lose elasticity and adhesion, causing heaters to slip or tilt — a condition that can expose the element above the waterline and create a fire or burn hazard.

Each holder consists of a rubber suction cup and a plastic clip that grips the heater body. The set fits most common heater diameters from 14mm to 22mm, covering the majority of submersible glass and titanium heaters on the market. Both vertical and angled mounting positions are accommodated by the swivel design of the clip.

Keeping spare suction cups on hand is recommended practice for any aquarist, as they are inexpensive insurance against heater positioning failures.
