Description
The Pentair Oval Closure (154576Z) is the OEM replacement closure for Triton C-3 fiberglass sand filters manufactured after March 1997, fitting models TR100C-3 and TR140C-3.
IMPORTANT: DATE-OF-MANUFACTURE QUALIFIER
This closure fits Triton C-3 sand filters manufactured after March 1997 only. If your filter was manufactured before that date, this part is not confirmed compatible. Check the date code on your filter tank before ordering.
The oval closure seals the tank opening on the Triton C-3 fiberglass sand filter, maintaining pressure integrity during filtration. A damaged or deteriorated closure can result in water loss, pressure drop, and compromised filtration performance. Replacing it with the correct OEM part restores a proper seal to the filter tank.
