Pentair 350013Z Lid O-Ring

The Pentair 350013Z is a replacement lid O-ring designed for compatible Pentair pool pump models. It provides a secure, leak-proof seal under the strainer lid or trap housing to maintain proper circulation.

Key Features

  • OEM-replacement O-ring for select Pentair pump models.
  • Ensures tight seal under pump lid or strainer cover to avoid air intake or leaking.
  • Easy to install — suitable for service calls or on-hand inventory stocking.

Specifications

  • Part Number: 350013Z
  • Material: Buna-N (nitrile) rubber (approx.)
  • Typical Application: Replacement lid seal for Pentair WhisperFlo, IntelliFlo, Challenger and compatible pumps.

Installation & Usage Notes

Power off the pump and relieve system pressure. Remove the pump strainer or trap lid, clean the seating surface thoroughly, remove the old O-ring and seat the new one evenly in the groove. Re-assemble the lid, restore circulation and inspect for proper seal and no leakage or air entering the system.

Maintenance Tips

  • Inspect the O-ring annually for flattening, cracking or chemical damage—replace as needed.
  • If you observe bubbling at the pump lid, loss of prime, or leaking under the lid, the O-ring seal may have failed.
  • Keep this O-ring in your parts inventory to support quick pump rebuilds or maintenance visits.

Why Choose This Seal?

For pool professionals, service technicians and homeowners, the Pentair 350013Z Lid O-Ring offers a cost-effective and OEM-matched solution to restore or maintain sealing performance in Pentair pump systems—helping preserve circulation efficiency, prevent air intrusion and ensure longer pump life.
