Specifications

  • Brand: Rheem
  • Part Number: AP13164-3
  • Type: Heat Trap Nipple
  • Size: 1" x 4"
  • Connection Type: NPT (National Pipe Thread)

Key Features

  • 1-Inch NPT Connection: Provides a secure and leak-resistant threaded connection compatible with standard pipe fittings
  • 4-Inch Length: Designed to fit correctly within compatible Rheem water heater configurations
  • Heat Trap Design: Helps reduce standby heat loss by limiting thermosiphoning, which improves overall water heater efficiency
  • Genuine Rheem OEM Part: Ensures proper fit, function, and reliability for supported Rheem water heater models

What Is a Heat Trap Nipple?

A heat trap nipple is installed at the hot and cold water connections of a water heater. It uses an internal dip tube or valve mechanism to prevent the natural convection of hot water out of the tank when no hot water is being used. This reduces energy waste and helps maintain the water temperature more efficiently, lowering operating costs over time.

Important Notes

  • This is a genuine Rheem OEM replacement part — always verify compatibility with your specific water heater model before ordering
  • Professional installation is recommended to ensure proper fitment and to avoid damaging existing plumbing connections
  • NPT threading requires appropriate pipe tape or thread sealant for a watertight seal during installation
