This flat gasket is intended exclusively as a spare part for the Astral AS 599 multiport valve (code 20569) and ensures a watertight seal at the valve connection point.
The exact shape and dimensions of the gasket match the manufacturer’s original, so installation is quick and results in a flawless seal of the joint.
The gasket is made of a material resistant to chlorinated water and the chemical additives commonly used in pool water treatment.
Replacing the gasket every time the valve is dismantled is a basic preventive measure that extends the service life of the entire filter assembly and prevents failures.
