Pentair 355330 Strainer Pot Flange O-Ring — For Tagelus® & Challenger® Pumps

🧰 Keep your pump system sealed and primed with the Pentair 355330 Flange O-Ring, designed for the strainer pot flange connection on Tagelus® and Challenger® pump models.

🔹 OEM Replacement O-Ring — Ensures a tight, leak-free seal between the pump strainer pot and volute housing.

🔹 Compatible With Pentair Pumps — Specifically fits Tagelus® and Challenger® high-performance pump models.

🔹 Prevents Leaks & Air Intrusion — A worn flange O-ring can cause priming issues or water loss—replace during pump service or when sealing issues are detected.

🔹 Durable, Chemical-Resistant Material — Built to withstand pool chemicals, high flow rates, and temperature fluctuations.

🔹 Easy to Install — Fits snugly in the flange groove—use a silicone-based lubricant (not petroleum-based) to enhance sealing and extend O-ring life.

Fits:
• Pentair Tagelus® Pumps
• Pentair Challenger® Pumps
• May fit other Pentair systems with compatible strainer pot assemblies (verify before purchase)

A critical part of any pump rebuild or seal kit, the 355330 Flange O-Ring helps ensure your system operates efficiently and leak-free.
