OLI discharge valve seal. External diameter 6cm, internal diameter 2.5cm.

The rubber seal is the part responsible for ensuring the watertightness of the flush valve inside the cistern.

This part needs repair because, when this rubber degrades or accumulates limescale, the toilet starts to "leak water" continuously into the bowl.

Compatible models: used in various OLI mechanisms, including the OLI80, Giada, Better, Diamante models and dual flush systems.

Material: made of high-resistance rubber.

Outer diameter: 6cm.

Inner diameter: 2.5cm.
