OEM Goodman Liquid Line Cap w/ O-Ring for ARPF486016CA — B9102097

The Goodman B9102097 is an OEM liquid line cap supplied with a sealing O-ring, used to close and protect the refrigerant liquid line service port on ARPF486016CA air handlers. This small part is a critical secondary seal: it prevents refrigerant seepage past the Schrader valve and keeps moisture and debris out of the service port between service visits.

OEM vs. Generic

Caps with the correct thread pitch and a properly durometer-rated O-ring are essential for a refrigerant-tight seal. The OEM B9102097 ships with the matched O-ring already sized for Goodman service ports, while generic caps may use the wrong seal material or omit the O-ring entirely, inviting slow refrigerant loss. At this price point, OEM is the obvious choice.

Installation

Difficulty: Easy. Hand-tighten onto the service port and snug with a wrench—no system evacuation required. Replace any time the cap is missing, cracked, or its O-ring is brittle. A 2-minute job; always verify the Schrader core itself is not leaking.
