Product Overview

The Pentair 154856 Triton buttress thread closure kit serves as the access lid assembly for Triton sand filter tanks. Installed at the dome opening of the filter, the closure seals the tank while maintaining the internal pressure required for effective sand filtration.

The 8.5-inch buttress thread design allows the closure to securely fasten to the filter tank while remaining removable when maintenance is required. This access point is used when replacing filter sand, inspecting internal components, or performing routine service. Replacing a worn or damaged closure kit helps restore leak-free operation and ensures reliable performance of Triton pool and spa sand filtration systems.
