Hayward Star-Clear C-500 replacement filter cartridge

Looking for a replacement cartridge for a Hayward Star-Clear C-500? The compatible Pleatco part is PA50, which cross-references to Unicel C-7656. Check the specs below against your old cartridge, then compare prices.

Cross-reference

Sources: Pleatco Catalog & Cross Reference Guide, BackyardCityPools Hayward cross-reference. Always compare the length, outside diameter and center openings of your old cartridge before ordering: manufacturers revise parts, and similar-looking cartridges differ by fractions of an inch.

How to confirm the fit

1. Find the model name on your filter tank’s label, or the part number printed on the end cap of the old cartridge.
2. Measure the old cartridge: overall length (end cap to end cap), outside diameter, and the openings at top and bottom (open hole, closed, or handle).
3. Match all three to the specs above. See how to measure a filter cartridge.

When to replace it

Most pool cartridges last about 1-3 seasons (often around 2,000 hours of run time). Replace sooner if pleats are torn, flattened or permanently discolored, the end caps are cracked, or the pressure gauge climbs quickly after every cleaning. See when to replace a filter cartridge.

Cleaning between replacements

Rinse with a garden hose from top to bottom, working between the pleats; soak in a filter cleaner periodically to remove oils and scale. Never use a pressure washer: it damages the fabric. Full guide: how to clean a pool filter cartridge.
