Product Overview
The Waterway 319-4100 Lid, Nut & O-Ring Kit is a service replacement assembly for Champion and SMF series pool pumps. The pump lid and O-ring work together to create an airtight seal at the strainer pot, allowing the pump to maintain proper prime and consistent water flow. A secure locking nut ensures the lid remains tightly fastened during operation.
Over time, lids may crack, O-rings can flatten or deteriorate, and locking mechanisms may wear from repeated service access. Replacing these components with the 319-4100 kit restores reliable sealing performance and supports proper pump function. When properly installed and lubricated with a compatible O-ring lubricant, this kit helps maintain leak-free operation and optimal circulation system performance.
