The Goodman B9102097 Liquid Line Cap with O-Ring is a genuine OEM service-port cap for Goodman WGPH4543AMAB packaged gas/electric units. It seals the liquid line service valve, providing a secondary leak barrier over the Schrader core. A missing or worn cap — or a dried-out O-ring — is a common slow-leak point that lets refrigerant escape and moisture enter. This replacement restores a positive, leak-tight seal.

OEM vs. Generic

The OEM cap and O-ring are sized to Goodman's exact thread and groove, compressing evenly for a reliable seal. Generic caps may use the wrong O-ring durometer or thread pitch, leading to weeping joints. For refrigerant integrity, OEM is the better long-term value.

Install Difficulty

Very Easy (1/5) — Hand-thread the cap onto the service port and snug with a wrench to the O-ring seat; do not overtighten. Under 5 minutes. No system recovery required — this caps the port, it does not break the refrigerant seal.
