About This Item
The Pentair Strainer Pot Flange O-Ring (355330Z) is the OEM replacement seal for the strainer pot flange on Tagelus fiberglass sand filters and Challenger High Flow pumps.
⚠️ IMPORTANT: VERIFY FIT FOR TAGELUS FILTER MODELS
This O-ring measures 1/8 in. cross-section × 2-3/8 in. inside diameter and is confirmed for Tagelus styles 11A and 11B only. If your Tagelus filter is a different style variant, verify against the part number stamped on your original O-ring before ordering.
This O-ring seals the strainer pot flange on the applicable filter and pump housings. A failed or deformed flange O-ring allows air to enter the system or water to leak at the strainer pot joint, disrupting prime and reducing pump efficiency. Replacing this O-ring restores a pressure-tight seal at the strainer pot connection point.

Pro Tip
Before ordering, compare the inside diameter and cross-section of your existing O-ring against the confirmed 2-3/8 in. i.d. × 1/8 in. cross-section specification — dimensions vary across Tagelus style variants. If you are servicing a Challenger High Flow pump, cross-reference your model number against the Fits Into table above. When the pump is open for service, it is good practice to replace the strainer lid O-ring at the same time to avoid a second disassembly for a part that has seen the same service hours.
