The Goodman B9102097 Liquid Line Cap with O-Ring is a genuine OEM sealing fitting for the liquid line service connection on Goodman ARPF496116CA air handlers and compatible coil sections. The pre-installed O-ring provides a refrigerant-tight seal, protecting the charge and keeping moisture and contaminants out of the system.
This genuine OEM cap ships with the correct durometer O-ring sized to the exact thread and groove of the Goodman liquid line port. Generic caps with mismatched O-rings are a common source of slow refrigerant leaks and failed pressure tests. The OEM fitting guarantees a reliable, leak-free seal rated for system pressures.
A missing, cracked, or hardened cap and O-ring allows refrigerant seepage and contamination, degrading capacity and risking compressor damage. A fresh sealed cap restores integrity to the line set.
Easy (1/5). Ensure the line is properly serviced, seat the new O-ring, and torque the cap to spec by hand or with a wrench. Refrigerant work should be performed by an EPA-certified technician. Confirm your model number before ordering.
