Protect Your Pump with Reliable Seals and O-Rings

Your pool pump is the heart of your circulation system, keeping water moving through filters, heaters, and sanitizing equipment. But even the best pump can’t run efficiently without healthy seals and O-rings. These small but critical components prevent leaks, maintain suction, and protect your motor from water damage.

At Benchmark Pool Supply, we carry a wide range of pool pump seals and O-rings for all major brands, including Pentair®, Hayward®, Jandy®, and Sta-Rite®. Whether you need a replacement lid O-ring, a pump housing gasket, or a full seal kit, we make it easy to keep your system watertight and working at peak performance.

Protect your pump from leaks by pairing seals and O-rings with Pump Parts, Pump Baskets, and Pool Pumps.

Why Pump Seals & O-Rings Matter

  • Prevent Leaks – Stops water from escaping at connection points.

  • Protect Motors – Prevents water from reaching electrical components.

  • Maintain Prime – Ensures suction power for proper circulation.

  • Extend Pump Life – Reduces strain on moving parts and bearings.

  • Cost-Effective Maintenance – Affordable replacements that prevent expensive pump repairs.

Common Pool Pump Seals & O-Rings

1. Lid O-Rings

  • Found on pump strainer baskets.

  • Ensure an airtight seal for easy priming.

  • Should be lubricated regularly and replaced when cracked or stretched.

2. Housing Gaskets

  • Seal the pump body where two halves connect.

  • Prevent leaks that reduce efficiency and strain motors.

3. Shaft Seals

  • Protect the motor by preventing water from leaking along the pump shaft.

  • One of the most important seals to replace during pump service.

4. Diffuser O-Rings

  • Ensure water flows correctly through the impeller and diffuser.

  • Essential for maintaining proper pressure and flow.

5. Complete Seal Kits

  • Include multiple O-rings, gaskets, and shaft seals.

  • Ideal for a full pump rebuild or seasonal maintenance.

Signs It’s Time to Replace Pump Seals & O-Rings

  • Visible cracks, brittleness, or flat spots.

  • Persistent air bubbles in the pump basket.

  • Loss of prime or weak suction.

  • Water leaking around the pump housing or motor.

  • Increased pump noise or overheating.

Maintenance Tips for Seals & O-Rings

  • Lubricate Regularly – Use a pool-safe silicone lubricant, never petroleum jelly.

  • Inspect Seasonally – Check all seals during pool opening and closing.

  • Replace in Sets – For older pumps, replace all O-rings at once for best performance.

  • Keep Spares on Hand – Small, affordable parts that prevent downtime.
