Pentair strainer pot lid replacement 355301 – clear OEM pool pump cover, leak-resistant seal

Pentair 355301 is a genuine replacement strainer pot lid designed to restore a secure, leak-resistant cover to compatible Pentair inground pool pumps.

This replacement lid fits Pentair strainer pots and is intended to replace cracked, cloudy, or damaged covers that compromise pump performance and visibility. Made by Pentair, the OEM part maintains original fit and function so you can avoid makeshift fixes and reduce downtime. The lid helps preserve the basket chamber seal, lets you inspect debris without removing the lid, and works with existing clamps and gaskets when those components are in good condition.

How will this lid restore my pump’s functionality?

Replacing a worn or broken strainer pot lid prevents air leaks and maintains proper suction so the pump runs as intended. A correct, tight-fitting lid also protects the skimmer basket area from contaminants and allows easy visual checks of debris build-up.

• OEM Pentair fit reduces risk of misalignment or stress on clamps.
• Clear or translucent material enables quick basket inspection.
• Preserves the pump’s original sealing surface for gaskets.

Which pumps and situations is the 355301 lid compatible with?

This lid is made for Pentair strainer pots used on many inground pool pumps; compatibility depends on the exact pump model and pot size. It’s intended as a direct replacement when the original lid is cracked, warped, or cloudy and when the pot’s threads or clamp surfaces match the OEM design.

• Designed for Pentair inground pump strainer pots of matching diameter.
• Best used when existing gasket and clamp are serviceable.
• Not a universal fit — verify dimensions with your pump manual.

How easy is installation and what tools do I need?

Installation is straightforward for anyone comfortable with basic pool pump maintenance: drain the strainer pot below the lid line, remove the old lid, inspect the gasket, then seat the replacement and secure the clamp or threads. Minimal tools are required, typically a screwdriver or wrench for the clamp and a soft cloth for cleaning sealing surfaces.

• Simple hand tools — screwdriver or wrench for clamps.
• Replace gasket if worn to ensure a proper seal.
• Inspect sealing surfaces and clean before installing.

What should I check before ordering this replacement lid?

Confirm the strainer pot diameter, clamp type, and whether your pump uses Pentair’s OEM lid design. Measure your existing lid or consult your pump’s parts diagram to ensure the 355301 matches; if in doubt, compare part numbers or contact a pool professional.

• Verify part number on existing lid or pump parts list.
• Measure pot diameter and clamp engagement style.
• Ensure gasket condition — replace gasket if brittle or flattened.

Who is this for: This replacement strainer pot lid is aimed at pool owners, service technicians, and maintenance professionals who need an OEM-quality cover for Pentair inground pump systems. Choose the 355301 when your current lid shows cracks, leaks, or clouding and you want a direct Pentair replacement to maintain pump reliability and safe, inspectable operation.
