When a filter's manifold or air-bleed assembly fails, filtration performance and circulation can suffer. This replacement top manifold is manufactured to fit FNS Plus 24, 36, 48 and 60 D.E. pool and spa filters as well as Titan RPM and 5000 Series D.E. filters, offering a direct-fit swap for the OEM 59023700 part number. Built from rugged materials and inspected to meet performance standards, it ships with the necessary air bleed tube and bleeder screen cap so you can replace the assembly quickly.

How does this manifold restore proper filter operation?

Replacing a damaged or leaking top manifold with this unit re-establishes correct air bleeding and internal flow paths, which helps maintain consistent pressure and filter efficiency. The integrated air-bleed assembly vents trapped air, reducing air locks that can disrupt pump performance.

• Direct compatibility with FNS Plus and Titan D.E. filter models for easy installation.
• Includes air bleed tube and bleeder screen cap so the assembly is ready to install.
• Designed to restore correct internal flow and prevent pressure spikes from trapped air.

What parts come in the package and which part does it replace?

The package contains the top manifold, an air bleed tube, and an air bleeder screen cap so you won’t have to source extra pieces. It serves as a replacement for part number 59023700 and matches the mounting points and ports used by the listed filter models.
