OEM Goodman Liquid Line Cap w/ O-Ring for WPC4430AHAB — B9102097

Goodman B9102097 Liquid Line Cap with O-Ring

The B9102097 is a genuine OEM Goodman liquid line service-valve cap, supplied with its sealing O-ring, for the WPC4430AHAB packaged air conditioner. This cap threads onto the liquid-side service port and is the system's secondary refrigerant seal — its bonded O-ring prevents slow refrigerant loss at the Schrader valve and keeps moisture and debris out of the sealed system. A missing or dry-rotted cap is a common, overlooked cause of gradual charge loss.

OEM vs. Generic

The genuine OEM cap arrives with the correct durometer O-ring already matched to the port — no guessing on seal size. Generic caps frequently ship without an O-ring or with a mismatched ring that won't seat, risking leaks. This is the factory-spec leak-tight seal.

Installation Difficulty

Very Easy — hand-thread onto the service port and snug with light wrench pressure. No tools or refrigerant handling required for the cap itself; under 5 minutes.
