HQPASFY Top Manifold for Pentair FNS Plus 24–60 — Replacement with Air Bleed, Reinforced Plastic

The HQPASFY 59023700 top manifold with built-in air bleed assembly replaces the original manifold on Pentair FNS Plus (24, 36, 48, 60) and compatible Titan D.E. filters to restore filtration performance and simplify air removal.

If your D.E. filter is losing suction, leaking around the top, or frequently trapping air, swapping in a fresh top manifold can bring back efficient, reliable filtration. This HQPASFY replacement includes the top manifold, an internal air bleed tube, and an air bleeder screen cap sized to fit common FNS Plus and Titan RPM/5000 series housings. It's molded from reinforced plastic and redesigned in known weak spots so it resists cracking and extends the working life of your pool or spa filter.

How does this manifold restore my filter's performance?

Worn or cracked manifolds let air enter the filter, interrupting flow and reducing cleaning efficiency. The HQPASFY unit reestablishes a sealed distribution point at the top of the cartridge assembly so water flows evenly through the D.E. elements again. The included air bleed components help purge trapped air quickly during startup.

• Replaces OEM 59023700 top manifold for Pentair FNS Plus 24–60 models
• Includes internal bleed tube and bleeder screen cap for complete assembly
• Redesigned to reduce common failure points and improve sealing

What materials and build changes improve durability?

HQPASFY uses a heavier, high-strength plastic formulation and adds targeted process improvements where original parts typically fail. Thicker wall sections and reinforced ribs distribute stress more evenly so the manifold tolerates long-term pressure cycles. These upgrades reduce hairline cracks, deforming, and premature breakage under normal pool conditions.

• Thickened, high-strength plastic resists cracking and impact
• Strengthened structural ribs at stress points for longer service life
• Manufacturing improvements based on common OEM failure patterns

Is installation complicated and what comes in the package?

Installation is straightforward for anyone familiar with routine filter maintenance: drain, open the filter, replace the top manifold and reinstall internal parts. The package supplies everything needed for the top-side replacement so you won’t be missing the bleeder hardware. Follow your filter’s service manual for torque specs and gasket checks to ensure a consistent seal.

• Box includes top manifold, internal air bleed tube, and air bleeder screen cap
• Packaged dimensions 15.94 x 15.55 x 3.82 inches; weight 2.4 pounds
• Simple swap for FNS Plus 24, 36, 48, 60 and compatible Titan RPM/5000 series

How will I know this is the right replacement for my filter?

This HQPASFY assembly was designed to match the fit and function of Pentair 59023700 manifolds used on FNS Plus models and some Titan D.E. filters. Check model numbers on your existing manifold or your filter lid to confirm compatibility before ordering. If the original part number matches or your filter manual references 59023700, this is the intended replacement.

• Compatible with Pentair FNS Plus 24, 36, 48, 60 D.E. filters
• Also fits Titan RPM and 5000 Series D.E. filter housings
• Black finish matches common factory components for a clean install

Who is this for: Pool and spa owners, maintenance pros, and backyard technicians who need a reliable, cost-effective replacement for a failing top manifold. If you want to avoid recurring air problems, restore circulation and filtration efficiency, and extend the life of your D.E. filter without replacing the entire tank, this HQPASFY 59023700 top manifold kit offers a targeted repair with improved materials and convenient included hardware.
