The Goodman B1796632 Seal and Nut (3/8 in.) is a genuine OEM sealing kit for ARUF061-00A-1 air handlers. This 3/8-inch seal and nut assembly creates a leak-tight connection at refrigerant or drain fittings, preventing refrigerant loss and moisture intrusion that can degrade system efficiency over time.
Seals and nuts must match thread pitch and sealing-surface dimensions exactly or the joint will weep. Off-brand hardware is a common source of slow leaks. The genuine OEM B1796632 guarantees correct thread fit and a durable, leak-free seal at the factory connection point.
Difficulty: Easy to Moderate (2/5). Replacing the seal and nut at a drain fitting is a quick 15–20 minute job. If the fitting is on the refrigerant circuit, an EPA-certified technician should perform the work, as it requires recovery and recharge. Always inspect the mating surface and torque the nut to spec.
