The Goodman B1796632 Seal and Nut (3/8 inch) is a genuine OEM sealing fitting designed for the ARPF486016AB air handler. This assembly creates a leak-tight connection on the 3/8" refrigerant line, combining a precision-machined flare nut with a matched seal to prevent refrigerant loss at the joint. A degraded seal is a common cause of slow refrigerant leaks, reduced cooling capacity, and compressor stress.

OEM vs. Generic

This genuine Goodman OEM seal and nut is dimensionally matched to the factory line set for a guaranteed leak-free seal. Generic 3/8" fittings vary in thread pitch and seal durometer, which can lead to repeat leaks and refrigerant top-offs. OEM ensures the correct seat geometry and preserves your equipment warranty.

Installation Difficulty

Moderate to Hard — Professional Recommended. Replacing a refrigerant line seal involves recovering charge, swapping the fitting, leak-checking, evacuating, and recharging. EPA-certified service is required for refrigerant work.
