O-Ring Depot

High-Performance Replacement Top Cover O-Rings

Keep your pool system running leak-free all season long with this professional-grade 4-pack of replacement top cover O-rings from O-Ring Depot. Specifically engineered to match the exact dimensions of Intex part number 10325, these 5" inside diameter (ID) seals provide a perfect watertight seal for your pool pump's top cover assembly.

They are basically the uncelebrated superheroes of your backyard pool paradise—because nobody wants to look like they are running a decorative water fountain out of their filter assembly when they're just trying to vacuum the pool floor.

⚠️ CRITICAL FITMENT CAUTION – PLEASE READ BEFORE ORDERING

Please measure before you order! These seals feature an exact 5" Inside Diameter (ID) and DO NOT fit newer pump models.

• The modern, larger 530 GPH pumps (603 / 25FP603) and the newer 1000 GPH pumps (637) use a completely different, smaller O-ring (Part Number 13413) which has an ID of approximately 4.5".
• If your pump is one of these modern versions, do not buy this listing—order part number 13413 instead! Be sure to double-check your old O-ring or measure the center groove width to save yourself an agonizing mid-summer shipping delay headache.

🛑 WATCH OUT FOR CHEAP OVERSEAS & CHINESE CLONES

Don't risk your pool season just to save fifty cents on cheap, low-grade rubber shipped from across the globe. The market is flooded with overseas knockoffs that look correct in photos but are manufactured with substandard materials, zero quality control, and incorrect tolerances.

• The Plasticizer Problem: Cheap imports often utilize highly diluted rubber mixtures that crack, warp, or expand like mush when exposed to direct sunlight and chlorine.
• Incorrect Sizing: Microscopic variations in overseas manufacturing mean those rings will either stretch out instantly or pinch when you twist the pump cover back on, leading to massive air traps.
• Support American Workers: These are proudly sourced and distributed right here in the USA. When you buy American, you are getting verified industrial-grade rubber engineered to last, while supporting domestic families instead of factory operations overseas.

🚀 Key Performance Features

• Watertight Sealing: Instantly stops air leaks and pressure loss through the pump top cover, ensuring your filter runs at maximum efficiency.
• Chlorine & UV Resistant: Formulated to withstand harsh pool chemicals, sanitizers, and direct sunlight without warping, drying out, or cracking prematurely.
• Industrial Resiliency: Flexible enough to create an airtight compression seal under hand-tightened or tool-secured lids, yet tough enough to withstand full pump pressure cycles.

Durable & Reliable Design

O-rings are like the donuts of the industrial maintenance world, except they are significantly less delicious and vastly superior at stopping your backyard from turning into an accidental wetlands reserve. These top cover seals drop right into the groove of your compatible pump lid, restoring factory-level pressure and stopping annoying drips instantly.
