The Waterway Filter Lid [Top Load w/ Plug & O-Ring Drilled] is a practical replacement sealing component for pool, spa, and bath equipment using compatible Waterway Plastics assemblies. Designed to help restore a clean seal between mating surfaces, this part is useful when servicing leaks, worn lids, valve bodies, filter housings, or other equipment connections where the original gasket or O-ring has become compressed, brittle, or damaged.

Because small sealing parts can have a major impact on system performance, replacing a worn seal with the correct part helps support better water containment, more dependable equipment operation, and easier ongoing maintenance. This component is especially helpful for service technicians and homeowners completing targeted repairs instead of replacing a larger assembly.

  • Replacement Waterway Plastics sealing component, part 550-5100D
  • Helps restore proper sealing performance on compatible equipment
  • Useful for service repairs, leak prevention, and routine maintenance
  • Designed for pool, spa, and bath equipment applications
  • Ideal when the existing gasket, lid seal, or O-ring is worn or damaged
