Goodman B9102097 Liquid Line Cap with O-Ring

The Goodman B9102097 is a genuine OEM liquid line service port cap with an integrated O-ring, designed for use on Goodman WPC4342AHAA air conditioning systems. This small but critical fitting seals the liquid line service port to prevent refrigerant leaks and keep contaminants and moisture out of the sealed system. A worn, lost, or cross-threaded cap is one of the most common (and most overlooked) sources of slow refrigerant loss, so replacing it with the correct OEM part restores a leak-tight seal and protects system charge.

Specifications

OEM Part Number: B9102097
Type: Liquid line service cap with O-ring
Brand: Goodman
Compatible Model: WPC4342AHAA
Equipment: Air Conditioner
Includes captive O-ring seal

OEM vs. Generic

The genuine Goodman part guarantees correct thread pitch and O-ring durometer for a verified leak-free seal on your specific unit. Generic caps may fit loosely or use lower-grade O-rings that degrade faster under refrigerant exposure, leading to repeat leaks. For a sealed-system component this small and inexpensive, OEM is the smart choice.

Installation Difficulty

Easy — Hand-tighten onto the service port; no tools or refrigerant handling required for the cap itself. A 2-minute job for any homeowner or technician.
