The B1796632 is a genuine Goodman 3/8-inch seal and nut assembly for ARUF061-00A-1A air handlers. This sealing kit creates a leak-tight refrigerant connection at the 3/8" fitting, preventing slow charge loss that degrades cooling capacity and efficiency over time. Replacing a worn or distorted seal during any line service restores a positive, factory-spec seal.
This genuine Goodman OEM seal is sized to the exact fitting durometer and bore. Off-brand seals can extrude, take a set, or weep under refrigerant pressure and temperature cycling. The OEM kit guarantees the correct fit on the first install.
Moderate — the seal itself swaps in minutes once the connection is open, but any refrigerant-side service requires recovery, evacuation, and recharge by an EPA-certified technician.
