Hayward TriStar strainer cover o-ring
It's always a good idea to replace the pump lid o-ring every other year to ensure proper seal. A small maintenance that, when overlooked, could cost you a replacement motor. Particularly important with the new (and not cheap!) variable-speed EcoStar Motors.
For use with: EcoStar SP3400VSP, TriStar VS SP3200VSP and TriStar SP3200EE/SP3200X/SP3600 pump series
Lid O-Ring fits Hayward EcoStar and TriStar Pumps
