The Pentair 154493 closure O-ring is a replacement sealing gasket designed for Triton II and Tagelus pool and spa sand filter systems. This 6-inch closure O-ring installs in the filter dome or closure assembly to create a watertight seal between the tank and lid. It helps maintain proper filtration pressure and prevents water leakage during normal filter operation.

Product Overview

The Pentair 154493 Triton filter closure O-ring is a critical sealing component used in several Pentair sand filter systems. Installed in the dome closure assembly, the O-ring forms the seal between the filter lid and tank body, preventing water leaks and maintaining the pressure required for efficient filtration.

This closure O-ring is commonly used with Triton II sand filters and Tagelus sand filters, as well as certain 1.5-inch HiFlow multiport valve assemblies. Its durable elastomer construction is designed to withstand exposure to pool chemicals, pressure fluctuations, and repeated compression cycles. Replacing worn or flattened O-rings helps restore leak-free operation and maintain reliable filtration system performance.
