About This Item
OEM Outlet Fitting for the Pentair ETi Series Gas Heater Heat Exchanger
The Pentair Heat Exchanger Outlet Fitting (461104) is the OEM replacement outlet fitting for the ETi 250 and ETi 400 gas pool and spa heaters, serving the heat exchanger plumbing assembly.
⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION 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.
The heat exchanger outlet fitting connects the heat exchanger assembly to the heater's discharge plumbing, directing heated water out of the heat exchanger and back into the pool or spa circulation loop. A cracked, corroded, or leaking outlet fitting compromises both heater efficiency and water-tight integrity at the heat exchanger connection point. Replacing this fitting with the correct OEM part restores a proper seal and maintains the designed flow path through the ETi heater.

Pro Tip
Before ordering, inspect the original fitting for a molded or stamped part number and confirm it matches 461104. The ETi 250 and ETi 400 share this fitting, but always cross-reference against your heater's parts diagram — available in the ETi installation and service manual — to confirm the correct outlet fitting position and orientation before disassembly. Have a licensed pool or HVAC technician perform the replacement.
