The Goodman B1796630 Flowrator Inlet Tube is a genuine OEM refrigerant metering component for WAHMS3636P4ABA air handlers. The flowrator (piston-style metering device) housing and inlet tube meter liquid refrigerant into the evaporator coil at the correct rate. Replace this tube when you have a restricted or damaged metering device, kinked or corroded tubing, or are servicing the coil and need to renew the inlet connection for a leak-free braze.

Specifications

Part Number: B1796630
Type: Flowrator inlet tube / refrigerant metering tube
Brand: Goodman (OEM)
Application: Evaporator coil liquid-line metering
Primary Fit: WAHMS3636P4ABA
Material: OEM-spec copper tubing

OEM vs. Generic

Metering geometry is critical — a generic tube with the wrong bore, length, or fitting can mis-meter refrigerant, causing poor cooling, coil freeze-ups, or high superheat. This OEM Goodman tube matches the exact diameter, length, and connection spec so the system charges and meters as the factory intended.

Install Difficulty

Advanced (4 of 5). Refrigerant-side work: requires EPA Section 608 certification to recover/evacuate/recharge, plus brazing skill. Not a DIY job. Recover refrigerant, braze under nitrogen, pull a proper vacuum, and recharge to spec.
