This Raypak sealing component, commonly referred to as a pump gasket, is specifically designed to prevent leaks in pool and spa pumps. It is composed of high-quality rubber material that ensures durability and longevity. The gasket measures 6 inches in diameter, making it compatible with a wide range of pump models. Its primary function is to create a watertight seal between the pump housing and the impeller assembly, thereby preventing water from leaking out of the system. This product is resistant to chemicals typically found in pools and spas, including chlorine and bromine. It's also able to withstand high temperatures, making it suitable for use in heated water systems.
