Product Overview

The Pentair 070942 flange gasket is an essential sealing component used in Pentair Tropic Isle pool and spa water heaters. Installed at the flange connection within the heater assembly, the gasket forms the seal that prevents water leaks while the heater operates under pressure.

Proper sealing at the heater flange connection is important for maintaining efficient heater performance and preventing water loss or pressure issues. Over time, heat cycles and chemical exposure can cause gaskets to wear or compress. Replacing the flange gasket restores proper sealing and helps maintain reliable operation of Tropic Isle heater models ranging from 120 to 420.
