Lochinvar 100217962 Diffuser Dip Tube 3/4 x 3 x 32 Inch Water Heater Replacement Part

The Lochinvar 100217962 is an OEM replacement diffuser dip tube designed for use in Lochinvar residential water heaters. Measuring 3/4" x 3" x 32", this diffuser dip tube is inserted into the water heater tank to direct incoming cold water to the bottom of the tank, where the heat source operates, ensuring efficient and consistent heating performance.

The diffuser design helps prevent thermal stratification within the tank — a condition where cold and hot water layers mix unevenly — which can reduce heating efficiency and contribute to premature tank wear. By promoting proper water circulation and temperature uniformity, this dip tube helps extend the service life of the water heater.
