KITONLA Manifold Top with Air Bleed for FNS Plus 24/36/48/60 - Reinforced PVC, Fits V38-140

This replacement manifold top fits a range of D.E. filters including FNS Plus 24/36/48/60, Titan RPM, Nautilus series and several 5000-series models. Constructed from reinforced PVC, the unit includes an internal air bleed tube and screen cap so trapped air and debris are kept out of the pool while maintaining reliable cartridge support. The assembly is compatible with listed OEM part numbers, making it a straightforward swap for tired or damaged manifolds.

How does this manifold top improve filter performance?

Replacing a worn manifold top eliminates leaks, restores stable pressure, and reduces air entrapment that can reduce pump efficiency. The integrated air-bleed assembly lets air escape from the filter housing without allowing debris back in, preserving filtration quality. As a result, the pump runs more smoothly and backwashing or cleaning cycles become more effective.

• Built-in internal air-bleed tube and screen cap to vent trapped air.
• Secure manifold design supports seven full grids plus one partial grid.
• Restores proper pressure readings and consistent flow through cartridges.

Will this fit my specific D.E. filter model?

This KITONLA manifold top is engineered to fit FNS and FNS Plus D.E. filter lines (24, 36, 48, 60) and compatible Titan RPM, Nautilus, and 5000-series units. It also matches multiple OEM replacement numbers, so you can cross-reference your old part before purchasing. Check your filter model and the compatible filter model numbers listed to confirm fitment.

• Fits Titan RPM, Nautilus FNS Plus, 5000 series and models 180006–180009.
• Replaces part numbers such as 59023700, V38-140, 25357-600-000 and more.

What materials and features ensure long-term durability?

The top manifold is molded from high-strength PVC for impact resistance and weather tolerance, which helps prevent cracking or corrosion in outdoor pool environments. The reinforced construction resists chemical exposure typical in pool systems, and the one-piece design reduces potential leak points. Together these features extend service life and reduce the need for frequent replacements.

• Premium PVC construction: shockproof and corrosion-resistant.
• One-piece manifold design minimizes joints and potential leaks.
• Air-bleed screen cap protects against debris ingress during operation.

How simple is installation and what comes in the package?

Installation is designed for DIY-friendly replacement without special tools: depressurize the filter, remove the clamp and lid, swap the old manifold for the new unit, then reassemble and inspect for leaks once the pump runs. The package includes every component needed to restore the manifold's air-bleed function, so no additional parts are typically required.

• Includes: top manifold, internal air-bleed tube, and air bleeder screen cap.
• One-piece replacement installs by hand after releasing filter pressure.
• Designed to match OEM connection points for straightforward swap-out.

Who is this for: This KITONLA manifold top is aimed at pool owners, service technicians and maintenance professionals who need a reliable, OEM-compatible replacement to restore filtration performance on FNS/FNS Plus and compatible D.E. filter systems. It’s ideal if you see persistent air in the system, inconsistent pressure, cracked or leaking manifold parts, or if you want to replace a discontinued OEM top with a durable aftermarket alternative.
