The Goodman B9102097 is a genuine OEM liquid line service cap supplied with its sealing O-ring for WPC4324AHAA air conditioners. This cap threads onto the liquid-line service port and provides the secondary, leak-tight seal that keeps refrigerant in and contaminants out. The included O-ring is the critical component — a brittle or missing O-ring is a common slow-leak point that quietly bleeds charge and degrades cooling performance.

Specifications

OEM Part Number: B9102097
Compatible Model: WPC4324AHAA
Brand: Goodman
Application: Liquid line service port cap
Includes: Cap with replacement O-ring
Function: Secondary refrigerant seal

OEM vs. Generic

The genuine OEM cap and O-ring are sized to the exact port threads and groove of the Goodman fitting, ensuring a proper compression seal rated for system pressure. Generic caps may thread on but use the wrong O-ring cross-section, allowing micro-leaks that are difficult to diagnose later.

Installation Difficulty

Easy (2/5). Seat the O-ring, hand-thread the cap onto the service port, and snug it to spec — do not overtighten. No refrigerant recovery is needed for the cap itself, but only handle service ports if you are comfortable around a charged system.
