The dip tube directs incoming cold water to the bottom of the tank, keeping it separated from the hot water at the top and maintaining efficient heat transfer throughout the unit. This kit measures 0.65 inches in diameter and 40.5 inches in length, with a 3\/4 inches NPT connection and a pack quantity of 5. It is installed by licensed plumbers or water heater service technicians during routine maintenance or when a failed dip tube causes complaints of lukewarm water or sediment discharge.\u003c\/p\u003e\n\u003cp\u003eThis dip tube kit is suited for water heater applications where the original tube has cracked, broken, or degraded over time. A failing dip tube is a common cause of reduced hot water output in tank-style water heaters. The 40.5 inches length is appropriate for standard tall-configuration residential tank units. The 3\/4 inches NPT fitting provides a direct, threaded connection to the cold water inlet port of the heater. The pack of 5 makes this kit practical for service companies stocking replacement parts for multiple installs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.65 inches diameter x 40.5 inches length for tall-tank fitment\u003c\/li\u003e\n  \u003cli\u003e3\/4 inches NPT threaded connection for standard cold water inlet ports\u003c\/li\u003e\n  \u003cli\u003ePack of 5 tubes per kit, suitable for service inventory\u003c\/li\u003e\n  \u003cli\u003eDirects cold inlet water to tank bottom to preserve hot water stratification\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement for restoring proper water heater performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement dip tube kit for compatible AO SMITH tank-style water heaters with a 3\/4 inches NPT cold water inlet.
