The Goodman B1796630 is a genuine OEM flowrator inlet tube for the evaporator coil in the Goodman AEPF303616AA air handler. This tube connects the refrigerant liquid line to the flowrator (piston) metering device that feeds the coil. Even minor corrosion, kinks, or improper sizing on this tube can disrupt refrigerant metering and degrade cooling capacity, so the correct OEM part keeps the system charged and balanced.
The OEM B1796630 is sized to the exact inner diameter and length the AEPF303616AA flowrator system requires, preserving correct refrigerant flow. Generic tubing risks restriction or improper braze fit-up. For accurate metering and a leak-free joint, OEM is recommended.
Advanced. Requires recovering refrigerant, brazing the new tube, pulling a vacuum, and recharging the system. EPA Section 608 certification required. Professional installation only.
