About This Item
The Pentair HX and Chimney Gaskets (475615Z) is the OEM replacement gas heat exchanger gasket service kit for the Pentair ETi® 400 Heater and UltraTemp 220 ETi — restoring the sealed combustion path between the heat exchanger and exhaust chimney.
⚠️ IMPORTANT: KIT LISTING — MULTIPLE GASKETS INCLUDED
This listing is a kit containing the heat exchanger and chimney gaskets as a set, not a single gasket. Order one kit per heater service.
⚠️ IMPORTANT: GAS HEATER COMPONENT — PROFESSIONAL SERVICE REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.
These gaskets seal the interface between the heat exchanger and the exhaust chimney assembly in Pentair gas heaters. A compromised gasket at either junction allows combustion gases to escape the sealed path, reducing heating efficiency and creating a safety hazard. Replacing this kit restores the integrity of the combustion and exhaust system to OEM specification.

Pro Tip
When the heat exchanger or chimney is removed for any reason — cleaning, inspection, or component replacement — replace this gasket kit as a matter of course rather than reinstalling the originals. Gaskets that have been compressed and heat-cycled rarely reseal reliably. Confirm the part number 475615Z against your heater's service manual or the original gasket before ordering, as gasket configurations can vary between heater generations. All service on this component must be performed by a licensed pool professional or qualified HVAC technician.
