Product Overview

The Pentair 154575 Triton filter closure serves as the access lid for Triton C and Triton C-3 commercial sand filter tanks. Installed at the top of the filter dome, the closure seals the tank opening while maintaining the pressure required for effective sand filtration.

The 8.5-inch buttress-thread design allows the closure to tighten securely into the filter tank while remaining easy to remove when maintenance is required. This access point is used when replacing filter sand, inspecting internal components, or servicing the filter assembly. The durable construction is designed for long-term operation in commercial pool environments where filtration systems operate under continuous pressure and chemical exposure.
