The Goodman B1796632 is a genuine OEM 3/8-inch seal and nut kit for AEPT030-00C-1A air handlers and compatible Goodman/Amana coils. This kit seals the 3/8" refrigerant connection at the coil, providing a leak-tight joint between the tubing and the metering or line-set fitting. Refrigerant seals harden and take a set over time; reusing an old seal after service is a common source of slow leaks and lost charge. Replacing the seal and nut together guarantees a fresh, properly torqued connection.
The genuine Goodman B1796632 uses the correct seal durometer and nut thread pitch for a guaranteed leak-free joint at rated pressure. Generic hardware-store seals may be the wrong material or tolerance, leading to refrigerant loss and repeat service calls. The OEM kit is matched to the factory fitting.
Easy–Moderate (2/5). Recover or isolate refrigerant as required, replace the seal, hand-start the nut, and torque to spec. Plan for 20–30 minutes plus leak check. Follow EPA refrigerant-handling rules before opening the connection.
