Generic PVC Thermowell [1/2" MPT] [5/16" Diameter] [4"] (990180)

The Generic PVC Thermowell [1/2" MPT] [5/16" Diameter] [4"] is built for targeted replacement work on compatible pool, spa, bath, or equipment systems where the right part number is important. This Generic item is associated with Heater Parts and is selected for heater service repair when the existing part no longer performs as expected or when a system rebuild requires a correctly matched component. The listed configuration includes 1/2" MPT, 5/16" Diameter, 4", making it easier to compare against the original part before ordering.

Part number 990180 should be matched against the existing component, owner’s manual, or equipment label before installation. Use this part when servicing heater performance issues, replacing aged components, or rebuilding a compatible assembly where water flow, electrical rating, and housing layout must line up correctly. Because heater parts can look similar across different brands and model years, confirming kilowatt rating, voltage, plug style, manifold size, or sensor requirements is especially important. For best results, inspect the surrounding seals, unions, gaskets, screws, or mating surfaces during replacement, since related wear can affect performance even when the main component is new.
