Ao Smith 100112272 Pex Dip Tube Kit 3/4 Npt

Product Description

The AO SMITH 100112272 is a PEX dip tube kit designed for use in residential water heater systems. The dip tube directs cold incoming water to the bottom of the tank, keeping it separated from the heated water at the top and maintaining thermal efficiency throughout the tank. This kit measures 3/4 NPT inlet connection by 47.3125 inches in length and is constructed from PEX tubing, which resists scale buildup and performs reliably in hot water environments. Licensed plumbers typically install this component during water heater service or repair.

This dip tube kit is suited for residential storage-style water heater installations where the original dip tube has failed, degraded, or fragmented. A deteriorated dip tube is a common cause of reduced hot water output, sediment in the water supply, or inconsistent water temperatures. The 47.3125-inch length accommodates standard tall-model residential water heater tanks. Installation is straightforward and is part of routine water heater maintenance and repair work performed by licensed plumbing contractors.

Key Features

• PEX construction resists scale and degradation in high-temperature water environments
• 3/4 NPT threaded inlet connection for standard water heater cold-supply ports
• 47.3125-inch length sized for tall residential water heater tank configurations
• Directs cold water to tank bottom to preserve hot water stratification and output efficiency
• Kit format includes components needed for a complete dip tube replacement

Compatibility

Designed as an OEM-style replacement dip tube kit for residential storage water heaters using a 3/4 NPT cold-inlet connection and requiring a dip tube length of approximately 47.3125 inches.

Installation Notes

A licensed plumber should perform dip tube replacement in accordance with local plumbing codes and IPC guidelines. Before beginning, shut off the cold water supply and connect the relief valve discharge line to a safe drain point. Power down or shut off the gas supply to the water heater before any internal service. Thread the 3/4 NPT fitting by hand first to avoid cross-threading, then snug with a wrench using thread seal tape or approved pipe compound on the threads.
