Goodman B1796630 Flowrator Inlet Tube

The B1796630 is a genuine OEM flowrator inlet tube for the Goodman WAHMS1824P4ABA air handler. This small but critical component feeds refrigerant into the flowrator (piston-style metering device) at the evaporator coil, ensuring the correct flow path and orientation for proper metering and heat exchange. A correct inlet tube is essential to maintaining rated cooling capacity and protecting the coil from improper refrigerant distribution.

Specifications

Part type: Flowrator inlet tube
Function: Refrigerant feed to metering device
OEM part number: B1796630
Brand: Goodman
Compatible model: WAHMS1824P4ABA

OEM vs. Generic

This genuine Goodman OEM tube matches the exact diameter, length, and bend geometry required by the WAHMS1824P4ABA coil assembly. Generic or improvised tubing can introduce restrictions, leaks, or misalignment at the flowrator — leading to poor cooling and potential warranty issues. OEM ensures a leak-tight, correctly metered connection.

Installation Difficulty

Advanced — Refrigerant work is involved. The system must be recovered, the tube brazed or fitted per the coil design, and the system evacuated and recharged. This part should be installed by an EPA 608–certified HVAC technician.
