The Goodman B9102097 Liquid Line Cap with O-Ring is a genuine OEM sealing component engineered for the WAHMS3743P4ACA air handler and compatible Goodman/Amana models. This cap seals the liquid line service port, protecting the refrigerant circuit from contamination, moisture, and leaks during storage, shipping, and service. The integrated O-ring delivers a positive, factory-spec seal that aftermarket plugs frequently fail to match.

Specifications

OEM Part Number: B9102097
Type: Liquid line cap with O-ring
Equipment: Air Handler
Compatible Model: WAHMS3743P4ACA
Brand: Goodman (genuine OEM)
Function: Refrigerant line port seal / leak protection

OEM vs. Generic

The genuine OEM cap arrives with a correctly sized, pre-installed O-ring rated for refrigerant service, ensuring a leak-tight seal the first time. Generic caps often use mismatched O-ring durometers or thread pitches that weep over time, risking refrigerant loss and warranty issues. For a small, critical sealing part, OEM is the safe choice.

Installation Difficulty

Easy (1/5). Hand-thread the cap onto the liquid line port and snug per manufacturer torque guidance. Always confirm the system is properly evacuated or isolated before servicing refrigerant connections; work should be performed by an EPA-certified technician.
