Goodman B9102097 Liquid Line Cap with O-Ring

The genuine OEM Goodman B9102097 liquid line cap with O-ring is the sealing cap for the liquid-line service port on the WPC4336AHAB and compatible Goodman/Amana condensing units. This cap is the secondary leak barrier for your refrigerant circuit — the captive O-ring forms a tight seal over the Schrader service valve, preventing slow refrigerant loss and keeping moisture and debris out of the system. A missing cap or dried-out O-ring is a common, often-overlooked source of low-charge complaints.

Fits Model: WPC4336AHAB

OEM vs. Generic

The genuine OEM cap matches the exact thread pitch and O-ring groove of your service valve, guaranteeing a leak-tight seal. Generic brass caps may have the wrong thread or a loose-fitting O-ring, allowing refrigerant to weep past the seal. For a part that protects your entire refrigerant charge, OEM is well worth it.

Installation Difficulty

Easy (1/5). Threads on by hand and snugs with a wrench — no system evacuation needed since it is the outer seal cap. Always confirm the underlying Schrader valve holds before relying on the cap.
