The Goodman B9102097 Liquid Line Cap with O-Ring is a genuine OEM refrigerant-side fitting engineered for the Goodman ARPF182416CA air handler and compatible ARPF-series coils. It seals the liquid line connection during shipping, service, and storage to keep moisture and contaminants out of the refrigerant circuit, protecting the metering device and coil from damage.
The genuine OEM B9102097 ships with the correct O-ring durometer and thread pitch to match Goodman's factory liquid line, ensuring a positive seal the first time. Generic caps often use a mismatched O-ring that can weep refrigerant or fail to seat fully, risking a slow leak and an avoidable service call. For a sealed refrigerant system, OEM is the safe choice.
Easy — hand-tight installation with a wrench for final seating. Recommended for HVAC technicians during evacuation, charging, or coil service. Always recover refrigerant and follow EPA Section 608 guidelines before opening the system.
