The Goodman B1796632 seal and nut is the genuine OEM 3/8-inch fitting hardware used to make a leak-tight refrigerant connection on ARUF042 series air handlers, including the ARUF042-00A-1A. The matched seal and nut maintain system pressure integrity and prevent refrigerant loss at the joint.

Using the correct factory seal is critical — even a minor leak at a refrigerant fitting degrades cooling capacity and can damage the compressor over time.

OEM vs. Generic

Installation Difficulty

Moderate. Replacing the seal at a refrigerant joint typically involves recovering and recharging refrigerant; best handled by an EPA-certified technician during related coil service.
