Optimum Pool Technologies motor seal kit for TriStar, EcoStar & EnergyFlo pumps — direct-fit with 2 seals & lube

This installation seal kit from Optimum Pool Technologies supplies the essential gaskets, pump seals and O-rings needed to service TriStar®, EcoStar® and EnergyFlo pool pump motors. Designed as a direct-fit aftermarket alternative, the kit brings together the most commonly replaced sealing components plus a lubricant pack so you can complete a motor seal replacement in one visit.

What parts are included and why they matter?

The kit gathers the primary sealing components that fail first in pump motor assemblies: the seal plate gasket, two ceramic/graphite pump seals, diffuser O-ring and lid O-ring. Replacing all these parts together helps restore proper sealing between the wet end and motor, reducing leaks and preventing premature motor wear.

• Seal plate gasket (O-529 style) to reseal the wet-end join.
• Two pump seals (PS-3890 compatible) for rotating shaft protection.
• Diffuser O-ring (O-83 compatible) to seal the diffuser housing.
• Lid O-ring (O-13 compatible) to secure the strainer lid.
• 1 oz. lubricant pillow pack for correct O-ring installation.

How does this kit fit my specific pump model?

This kit is made as a compatible replacement for common Hayward service kits such as GO-KIT80 and SPXHKIT100 and is intended for TriStar, EcoStar and EnergyFlo pumps from Hayward. Each replacement part matches the standard dimensions referenced by the OEM part numbers, making it suitable for the same motor generations listed in the compatibility notes.

• References common OEM numbers for correct cross-compatibility.
• Fits many SPX3200 and SPX4000-series configurations (post-2003 seal types).
• Works with both TriStar and EcoStar wet-end assemblies.

What tools and steps are needed for installation?

Basic hand tools and a clean workspace are usually sufficient: screwdriver or nut driver, pliers, and a torque wrench if re-installing to factory motor specs. The included lubricant eases O-ring seating; follow standard motor disassembly procedures and inspect the shaft and mating surfaces before reassembly.

• Hand tools: screwdrivers, pliers, socket set; light cleaning supplies.
• Use supplied lube to prevent pinched O-rings and ensure proper seal compression.
• Inspect shaft, shaft sleeve and housing for wear before installing new seals.

Will using a compatible aftermarket kit affect warranty or performance?

This Optimum Pool Technologies kit is an independent aftermarket replacement and not an OEM-manufactured Hayward product. When installed correctly, compatible kits provide the same sealing function as OEM parts, but check your equipment warranty terms—some manufacturers require OEM parts to preserve certain warranty conditions.

• Aftermarket compatibility designed to match OEM dimensions and materials.
• Does not come from the original pump manufacturer; branding used for reference only.
• Proper installation and inspection maintain performance similar to OEM seals.

Who this kit is for: Pool professionals and experienced DIYers who maintain Hayward TriStar, EcoStar or EnergyFlo pump motors and want a one-stop set of compatible replacement seals and O-rings. It’s ideal when you need to replace multiple sealing components at once to stop leaks, refresh worn seals, or complete a motor wet-end service without sourcing individual parts.
