The Goodman B1796632 is a genuine OEM 3/8-inch seal and nut assembly engineered for the ARPF486016BA air handler and other compatible Goodman/Amana air handling units. This small but critical component ensures a leak-free connection at refrigerant and drain fittings, protecting system efficiency and preventing moisture intrusion. A worn or missing seal is a common cause of nuisance leaks and reduced performance, making this an inexpensive but important repair.
Our genuine OEM B1796632 guarantees an exact dimensional and material match for a reliable seal, where aftermarket generics may vary in thickness and compression, leading to repeat leaks. For a sealing component, OEM fit is strongly recommended.
Easy — A basic DIY repair requiring only hand tools. Always shut off power and relieve system pressure before servicing.
