Description

The Pentair 178616 Compression Spring is a small but essential component that ensures your filter manifold applies even pressure across cartridges. It’s engineered for ease-of-use: simply drop it into the central post of your manifold during rebuild or maintenance. Because the spring is properly tensioned, it helps the filter maintain consistent flow and avoids cartridge shifting or bypass. No adjustments or calibration required beyond standard reassembly.
