The O-ring 56×5.3 mm is the sealing element located at the point where the inlet or outlet spigot connects to the body of the Elecro UV sterilizer. Its function is crucial for the water-tightness of the entire device at operating pressure.
Replacement of the seal is necessary when the connection is dismantled (for example when replacing the UV lamp) or if drops of water appear around the joints. The original size 56×5.3 mm guarantees a precise fit in the groove of the union coupling.
The material is resistant to chlorine, peroxide and other pool chemicals and retains its elasticity across the entire range of the system’s operating temperatures.
