Tapered rubber stopper, Ø 28 to 32 mm

Conical rubber stopper Ø28–32 mm

The conical rubber stopper has a diameter of 26/32 mm and functions as a plug (like a cork stopper). It is primarily used with commercial tray systems (for example, Ebb & Flow trays) to prevent water from draining until the tray is flushed through the drainage hole. 

Detailed specifications

• Type: conical rubber stopper, functioning like a cork stopper.
• Size: 26/32 mm (in the context of Ø 28–32 mm) — corresponds to the specified range.
• Application: Seals trays during flooding; after it is removed, fresh water can be added and the growing medium and residue flushed through the drainage hole.

Usage recommendations

• When inserted, the stopper completely seals the tray, allowing it to be flooded without leaks.
• Once you remove the stopper, the system automatically allows waste to drain. This makes it easier to clean and prepare the tray for reuse.

Benefits 

The rubber stopper is a practical, inexpensive solution for controlled filling and drainage of trays. It is easy to install and provides a reliable seal during filling, while removing it allows efficient flushing and cleaning without the need for additional mechanisms. This gives you maximum control over the irrigation cycle.

Installation and drainage

Compare the external dimensions with the installation space and check whether a drainage hole is already present. Ebb & Flow systems require compatible inlet and drainage connections, a reservoir, and cycle control.
