Description
Protect your Sta-Rite System 3 filter from water loss with the Aladdin O-485 Tank O-Ring, a precision-cut replacement gasket built for models S7M120, S7M400, S7S50, and S7D75. This seal sits between the upper and lower tank sections, creating a solid barrier that prevents drips and maintains full filtration pressure. Made from a hardy, chemical-tolerant compound, the O-485 holds its shape and elasticity through season after season of pool operation. Checking this gasket at every filter service and replacing it at the first sign of wear is one of the simplest ways to safeguard your equipment and avoid costly water waste.
