OEM Goodman Liquid Line Cap with O-Ring for WGHP4448AAE — B9102097

Goodman B9102097 Liquid Line Cap with O-Ring

The B9102097 is a genuine Goodman liquid line service valve cap supplied complete with its sealing O-ring, designed as an exact-fit replacement for the WGHP4448AAE packaged heat pump. This cap threads onto the liquid line service port and forms the secondary, leak-tight seal that protects the Schrader core and prevents slow refrigerant loss between service visits. Replacing a cracked, lost, or O-ring-degraded cap is one of the simplest and most cost-effective ways to stop a nuisance refrigerant leak.

OEM vs. Generic

The genuine Goodman cap and O-ring are sized to the exact thread pitch and groove dimensions of the WGHP4448AAE service valve, ensuring a true metal-to-metal and elastomer seal. Generic caps may strip threads or use an O-ring durometer that hardens and weeps over time. At this price point, OEM is the obvious choice.

Installation Difficulty

Easy — DIY friendly. No refrigerant work is required to swap the cap itself; simply remove the old cap, seat the new O-ring, and hand-tighten plus a quarter turn. If the underlying Schrader core or service port is leaking, have a licensed technician inspect it. Verify fitment against your unit nameplate before ordering.
