Technical Overview

These O-rings correspond to several long-running filtration systems used in residential and commercial pool and spa equipment.
Their function is to create a dependable seal at tank closures, manifolds, and related service points where water pressure and continuous circulation demand a stable, compression-tight gasket.

Applications & Function:

• Hayward Pro-Grid DE-2400-Z-5: Commonly installed in DE filter assemblies, this seal helps maintain the tank body closure, reducing the risk of bypass leaks during filtration cycles.
• Pentair / PacFab Nautilus, FNS, FNS Plus (192323): Used on pressure-side interfaces of the filter housing, supporting uniform sealing under variable pump loads.
• Pentair 51013500 (53102900 – pre-1990): Fits earlier filter configurations where the O-ring seats into a groove that requires consistent compression to maintain proper circulation.

Material Notes:

• EPDM Construction: Selected for its resistance to chlorinated water, ozone exposure, and higher temperature fluctuations often encountered in pool filtration environments.
• Maintains elasticity over repeated service cycles, reducing the need for premature replacement.
• Suitable for both routine maintenance and full filter-system rebuilds.

Installation Guidance:

Before installing, clean the channel or sealing surface to remove scale, debris, or residue from prior gaskets.
Lightly lubricate with an O-ring–safe silicone grease if recommended by the equipment manufacturer.
Seat evenly and avoid twisting the material. Reassemble the filter system according to official specifications for torque and closure sequence.
