Description
Restore a watertight seal on your Hayward filter with the Swimables SW-27-429 tank O-ring, a direct replacement for the DEX2400K. This O-ring sits between the filter tank body and its top lid, compressing evenly to create a leak-proof barrier that keeps water inside the filtration chamber where it belongs. Formed from flexible, chemical-resistant elastomer, it maintains its shape and sealing ability even after prolonged exposure to chlorine, muriatic acid, and other common pool chemicals. When an aging O-ring starts to crack, flatten, or let water seep past the lid, swapping in this Swimables replacement takes just minutes and immediately brings your filter back to full operating pressure and efficiency.
