Ao Smith 100112694 Pex Dip Tube Kit 3/4 Inch Npt

Product Description

The AO SMITH 100112694 is a PEX dip tube kit designed for residential water heater service and repair. The dip tube directs incoming cold water to the bottom of the tank, keeping it separated from the heated water at the top and maintaining consistent hot water output at the outlet. This kit measures 34.25 inches in length with a 3/4 inch NPT connection and a 4 inch outer dimension at the fitting end. It is an OEM-style replacement component installed by licensed plumbers during routine water heater maintenance or failure repairs.

This dip tube kit is suited for residential tank-style water heater applications using HT2-series configurations. The 3/4 inch NPT thread size is a common cold-water inlet size found on standard residential water heater tanks. The PEX construction offers resistance to scaling and cracking compared to older polypropylene dip tubes, making it appropriate for a range of water quality conditions encountered in residential installations.

Key Features

• PEX construction resists scaling and cracking in varied water conditions
• 34.25 inch length delivers cold water to the lower tank zone for efficient heat stratification
• 3/4 inch NPT connection fits standard residential water heater cold-inlet ports

Compatibility

Designed as an OEM-style replacement dip tube kit for AO SMITH HT2-series residential tank water heaters with a 3/4 inch NPT cold-water inlet. Consult the unit nameplate and service documentation to confirm fitment before installation.

Installation Notes

Dip tube replacement is a plumbing service task performed by a licensed plumber. Shut off the cold-water supply and de-energize or extinguish the heat source before removing the old dip tube. Use appropriate thread sealant on NPT threads per local plumbing code requirements. Do not overtighten the fitting, as PEX and plastic components can crack under excessive torque.
