Goodman B9102097 Liquid Line Cap with O-Ring

This genuine Goodman B9102097 liquid line cap with integrated O-ring provides a leak-tight seal for the refrigerant service port on the WGHP4418AAE air conditioner. The cap protects the Schrader valve from dirt and moisture while the captive O-ring delivers a secondary refrigerant-grade seal, preventing slow refrigerant loss that degrades cooling performance over time.

Specifications

OEM Part Number: B9102097
Brand: Goodman
Compatible Model: WGHP4418AAE
Type: Liquid line / service-port cap
Includes: Replacement O-ring seal
Function: Refrigerant port protection & leak prevention

OEM vs. Generic

The OEM cap arrives with the correctly durometer-matched O-ring sized for Goodman service ports, ensuring a positive seal. Generic caps often ship without an O-ring or with a mismatched seal, increasing the risk of slow refrigerant leaks. For sealing-critical applications, OEM is the safe choice.

Installation Difficulty

Easy — hand-tighten onto the service port after seating the O-ring. No tools or refrigerant handling required for the cap itself. Confirm the O-ring is clean and free of debris before installation.
