O-Ring for Hayward 300W Light Bulb

This O-ring is a precisely shaped sealing element designed for Hayward 300W pool lights. When replacing the bulb or after a longer period of operation, the seal may wear, leading to water ingress – replacing the O-ring reliably eliminates this problem. The material, resistant to the chemicals used in pool water treatment, guarantees a long service life. A correctly fitted O-ring is a key safety element of the entire lighting system. We recommend replacing it whenever servicing the light.
