The Goodman B9102097 liquid line cap is a genuine OEM refrigerant fitting for the APH1530M41AB heat pump and related Goodman/Amana systems. It seals the liquid line service port and includes the correct O-ring, providing a secondary leak-tight barrier that protects your refrigerant charge and keeps moisture and contaminants out of the sealed system.
The OEM B9102097 is machined to the exact thread pitch and depth of your port, and ships with an O-ring rated for refrigerant contact. Generic caps frequently use the wrong O-ring durometer or an imprecise thread, which can weep refrigerant over time and trigger slow-loss charge problems that are expensive to chase down. The genuine cap guarantees a proper metal-to-metal and O-ring seal.
Difficulty: Easy (1/5). Ensure the port is not under active service, seat the new O-ring, thread the cap on by hand, and snug it with a wrench per spec — do not over-torque. Install time is under 5 minutes. Have a certified technician handle any work that requires opening the sealed refrigerant system.
Genuine Goodman fitting for a secure, factory-correct seal on your APH1530M41AB.
