The Goodman B1796630 is a genuine OEM flowrator inlet tube made for the ADPF486016BA evaporator coil and compatible Goodman/Amana units. The flowrator (piston-style metering device) and its inlet tube control refrigerant flow into the coil, and correct sizing is critical to maintaining proper superheat, capacity, and efficiency.

  • Part Number: B1796630
  • Type: Flowrator inlet tube / refrigerant metering tube
  • Compatibility: Goodman ADPF486016BA evaporator coil and related models
  • Brand: Goodman (OEM)
  • Function: Routes metered refrigerant into the coil distributor

OEM vs. Generic: Refrigerant metering components must match the coil's design tonnage and orifice size. The OEM B1796630 guarantees the correct tube diameter and braze geometry, while generic substitutes can throw off superheat and reduce cooling performance. For a sealed-system repair, OEM is strongly recommended.

Install difficulty: Advanced — EPA certification required. Installation involves recovering refrigerant, brazing the tube into the coil circuit, evacuating, and recharging. This should be performed by a licensed HVAC technician. Plan 1–2 hours including evacuation and charging.
