The Goodman B9102097 Liquid Line Cap with O-Ring is the genuine OEM sealing cap for the liquid-line service port on the Goodman WGHP4448AAD packaged unit. The included O-ring provides the primary leak-tight seal, with the threaded cap acting as a secondary mechanical barrier against refrigerant loss — keeping the sealed system charged and protecting the Schrader core from contamination.
Specifications
- OEM Part Number: B9102097
- Brand: Goodman
- Compatible Model: WGHP4448AAD

OEM vs. Generic
The OEM cap ships with the correct O-ring durometer and thread pitch for a guaranteed seal. Generic caps frequently use mismatched O-rings that weep refrigerant over time. At this price point, there is no reason not to use genuine OEM.
Install Difficulty
Easy. Hand-tighten the cap onto the service port with a wrench to the final seat. Always verify the O-ring is seated and free of debris. No refrigerant recovery needed to replace the cap itself.
