The transparent lid is a genuine spare part for Cantabric sand filtration vessels. The transparent material allows a view into the upper part of the vessel and inspection of the level of filter sand or glass beads without the need to unscrew the lid.
The delivery also includes a corresponding seal that ensures the watertightness of the joint even at full filtration working pressure. The precise dimensions and thread match the original, so replacement is straightforward.
The lid is made of durable transparent plastic compatible with chlorinated pool water. We recommend replacing the lid immediately upon detecting cracks or deformation to prevent a failure under pressure.
