Pentair Replacement Screen Cap for Air Bleeder Assembly

The Pentair Replacement Screen Cap for Air Bleeder Assembly (part number 190106Z) is a small but critical protective component designed for the internal air relief plumbing of high-capacity Pentair pool and spa filters, including Clean & Clear Plus cartridge, Quad D.E., and EasyClean D.E. filtration systems. Positioned inside the filter tank at the topmost apex of the air bleeder tube, this specialized cap features an integrated fine mesh screen that permits trapped air to freely escape while actively blocking fine pool debris and filter media from entering and clogging the manual relief valve assembly. Molded from a high-density, chemical-resistant polymer to survive the turbulent, chlorinated internal environment of a pressurized filter shell, this component ensures the air-relief pipeline remains completely free of obstructions. Because of its compact, micro-sized structure, the screen cap is incredibly light, carrying an actual and shipping weight of approximately 0.20 pounds (about 3.2 ounces), making it an easy-to-install, highly efficient replacement part for safeguarding your system's pressure regulation.
