The Pentair N20-25 Seal Plate Gasket is a genuine replacement seal used in a variety of Pentair pool and spa pump assemblies. Installed between the seal plate and the pump housing, this gasket is responsible for creating a watertight barrier that prevents leaks and protects internal components from water damage.

Made from high-quality, chemical-resistant rubber, the N20-25 is engineered to withstand exposure to chlorine, high flow rates, and operational heat. Over time, worn or flattened gaskets can cause loss of pressure, visible leaks, or even motor failure—making this small part essential for maintaining your pump's integrity.
