The bulb cover gland nut is a small but functionally essential part of the 300W PT series pool light, which seals the point where the cable passes through the rear cover of the luminaire.
Proper sealing of the gland is crucial for the watertightness of the entire pool luminaire – a damaged or missing nut can cause water to enter the electrical part of the light and a short circuit. The original part meets the manufacturer’s precise dimensions and material specifications.
Replacing the gland nut is a simple service task that restores the watertightness of the light and extends its service life. It is recommended to inspect the gland during every service of the pool lighting.
