OEM Goodman Liquid Line Cap with O-Ring for WAHMS3636P4ACA — B9102097

The Goodman B9102097 Liquid Line Cap with O-Ring is a genuine OEM service fitting engineered for WAHMS3636P4ACA air handlers and compatible Goodman/Amana coil assemblies. It seals the liquid line service port to prevent refrigerant migration and moisture intrusion during shipping, storage, and service, helping protect the integrity of the sealed system until final connection.

The captive O-ring delivers a positive, leak-tight seal rated for standard R-410A and R-32 line pressures, eliminating the guesswork and slow leaks that come from generic plastic caps. Using the factory part keeps the equipment within its certified warranty specification.

OEM vs. Generic

Our OEM cap arrives with the correct O-ring durometer and thread pitch for a guaranteed seal and warranty compliance. A Generic equivalent saves a few dollars up front but often ships with a mismatched O-ring that weeps over time — a costly trade on a sealed refrigerant system.

Installation Difficulty

Easy (1/5) — Hand-thread onto the service port and snug with a wrench. No special tools or recovery required for capping. Verify the O-ring is seated before tightening.
