OEM Goodman Liquid Line Cap w/ O-Ring for WGPH4530AMAB — B9102097

The Goodman B9102097 Liquid Line Cap with O-Ring is a genuine OEM service fitting for Goodman WGPH4530AMAB package air conditioners. It threads onto the liquid line service port to seal the refrigerant access valve, protecting the Schrader core from contamination and providing a secondary leak barrier.

The included O-ring is the critical component — it forms the actual refrigerant-tight seal. A missing, dry, or cracked O-ring is one of the most common sources of slow refrigerant loss on package units. This OEM cap arrives with the correct durometer O-ring already fitted.

• Type: Liquid line service port cap
• Seal: Pre-installed O-ring
• Fit: Goodman WGPH4530AMAB and compatible models
• Function: Secondary leak seal + core protection
• Part Number: B9102097

OEM vs. Generic: Generic brass caps often ship without an O-ring or with the wrong size, leading to bottoming-out before the seal compresses. This genuine Goodman cap matches the port thread and seal profile exactly, so it torques to the correct stop and seals on the first try.

Install Difficulty: Very Easy (1/5). Hand-thread onto the liquid line port and snug with a wrench. No refrigerant recovery needed when the system core is intact. Replacement takes under 5 minutes.
