Pool Filter Parts – Cartridges, Grids, Valves & Seals

Keep Your Pool Crystal Clear with the Right Filter Parts

Your pool filter is one of the most important pieces of equipment in your backyard. It traps dirt, debris, and contaminants, keeping your water clean, safe, and inviting. But like all equipment, filters rely on small yet vital components — cartridges, grids, laterals, valves, O-rings, and gauges — that wear down over time. Replacing these parts promptly ensures your filter runs efficiently and extends the life of your entire system.

At Benchmark Pool Supply, we carry a complete selection of pool filter parts for cartridge, sand, and DE filters from trusted brands like Pentair®, Hayward®, Jandy®, and Sta-Rite®. Whether you need a new pressure gauge, backwash valve, or a full set of replacement cartridges, we make it easy to keep your water sparkling clear.

Efficient Operation – Prevents clogs, pressure issues, and unnecessary strain on pumps.

Cost Savings – Affordable parts reduce the need for costly equipment replacement.

Longer Equipment Life – Keeps your filter system running at peak efficiency.
