Ao Smith 100112695 Pex Dip Tube Kit 3/4 Inch Npt

Product Description

The AO SMITH 100112695 is a PEX dip tube kit designed for use in residential water heater systems. The dip tube directs incoming cold water to the bottom of the tank, improving heating efficiency by keeping cold supply water away from the hot water outlet at the top. This kit measures 40.75 inches in length with a 3/4 inch NPT connection and a 4 inch fitting dimension, making it a direct-fit replacement component. Installation is typically performed by licensed plumbers during water heater service or repair.

This dip tube kit is suited for HT2-series water heater applications. It is used when the original dip tube has failed, broken, or degraded — a common service issue in older tank-style water heaters. The PEX construction provides resistance to the high-temperature, high-pressure environment inside a water heater tank. Replacing a failed dip tube restores proper tank stratification and hot water delivery performance.

Key Features

• PEX construction resists high-temperature water heater tank conditions
• 3/4 inch NPT connection fits standard cold water inlet ports
• 40.75 inch length suited for HT2-series tank configurations
• 4 inch fitting dimension for proper inlet seating
• Restores correct cold water distribution within the tank

Compatibility

Designed as an OEM-style replacement dip tube kit for HT2-series AO SMITH residential tank water heaters with a 3/4 inch NPT cold water inlet.

Installation Notes

Installation should be performed by a licensed plumber. Before servicing, shut off the cold water supply and disconnect power or turn off gas to the water heater to prevent injury. Drain the tank as needed to relieve pressure before removing the old dip tube. Follow local plumbing codes, including applicable IPC requirements, when replacing water heater components.
