These suction cups were designed for use in many Aquael filters, heaters and pumps. They can also be adapted to fit other products depending on how those suction cups are used. The rims on top can be cut to fit other pumps and filters that use that type system or the centers can be drilled in the center to fit peg type attachment systems. These are deeper than most suction cups which provides a very strong suction attachment. They are generally used on heavier pumps and accessories requiring extra strength such as larger heaters, multi-piece accessories, heavy powerheads, pumps, etc.
