OEM Goodman Liquid Line Cap w/ O-Ring for WGPH4560AMAA — B9102097

Goodman B9102097 Liquid Line Cap with O-Ring

The Goodman B9102097 is a genuine OEM liquid line service-port cap, supplied complete with its sealing O-ring, for the WGPH4560AMAA packaged air conditioner. This cap threads onto the liquid-side service valve and forms the secondary seal that keeps refrigerant in and contaminants out after charging. The included O-ring is the critical part — a brittle or missing O-ring lets the system weep refrigerant over time, leading to low charge, poor cooling, and compressor strain.

OEM vs. Generic

OEM ensures the thread pitch and O-ring durometer match Goodman's service valve exactly. Generic caps sometimes use the wrong O-ring compound, which can swell or harden against the specific refrigerant and fail. The genuine B9102097 gives a leak-tight, factory-spec seal every time.

Installation

Difficulty: Easy (1/5). No tools beyond a wrench. Seat the O-ring, hand-thread the cap onto the service port, then snug it about a quarter-turn past finger-tight — do not overtighten. A few minutes of work. For best results, replace the O-ring whenever the system has been opened for service.
