The Goodman B1796632 Seal and Nut (3/8") is a genuine OEM sealing fitting for the ARUF060-00A-1A air handler. This assembly provides a leak-tight 3/8-inch connection where refrigerant or condensate-line fittings join the coil/cabinet. A hardened, cracked, or missing seal is a frequent cause of slow refrigerant leaks and nuisance service calls, so replacing it whenever a fitting is opened is good practice.
Seals are inexpensive but critical. The OEM B1796632 is matched to the exact thread pitch and seat of the ARUF060 fitting, ensuring a proper crush and long-term seal. Generic seals may use the wrong durometer or dimensions, leading to weeping joints. Always use the factory seal on sealed-system connections.
Easy to Moderate. The seal-and-nut itself installs in minutes with a wrench. However, if it serves a refrigerant fitting, EPA-certified handling and proper torque are required. For condensate or non-pressurized fittings, this is a quick DIY-friendly swap.
