About This Item

The Hayward Gauge Adapter (ECX12866) is the OEM replacement gauge adapter for Perflex Extended-Cycle DE Filters, providing the threaded interface that connects the pressure gauge to the filter tank.

This adapter seats into the filter body and accepts the pressure gauge assembly, allowing accurate monitoring of filter operating pressure. Replacing a damaged or stripped adapter restores a leak-free, readable pressure connection to keep your Perflex filter running at the correct service parameters.

Poolaroo Pro Tip

When installing the replacement gauge adapter, inspect the threads on the filter body for any damage before seating the new adapter. Apply PTFE thread tape to the adapter threads to ensure a watertight seal and prevent pressure gauge readings from being affected by minor weeping at the connection point.
