The HARMSCO INC 545 is a stainless steel filter lid with a welded handle, designed for use on compatible Harmsco filtration equipment. The welded handle construction provides a secure grip for removal and reinstallation during routine filter service. Built from stainless steel, this lid resists corrosion in wet, chemical-laden environments typical of pool and water treatment applications. It is installed by pool service professionals and water treatment technicians as a replacement component when an existing lid is damaged, cracked, or missing its handle.
This lid is suited for commercial and residential pool filtration systems that use Harmsco filter housings requiring a stainless steel top closure. It is a direct-replacement part for service calls where the original lid has failed or been lost. The welded handle eliminates the need for additional tools during routine cartridge or media changes, making it a practical replacement in high-service-frequency installations.
Designed as an OEM-style replacement lid for compatible Harmsco filter housings used in pool and water treatment filtration systems.
Installation is typically performed by a licensed pool service technician or plumber. Before removing the existing lid, shut off the pump and relieve any pressure in the filter housing according to the equipment manufacturer's procedures. Inspect the lid seat and any sealing surfaces for wear or debris before seating the replacement lid. Follow all applicable local plumbing codes and the filter housing manufacturer's guidelines during service.
