The Goodman B9102097 is a genuine OEM liquid line service-port cap supplied with its sealing O-ring, designed for Goodman CPC150 series air conditioners including model CPC150XXX7BXXXAA. This cap provides a secondary leak-tight seal over the service valve, preventing refrigerant loss and keeping contaminants out of the access port.
This genuine Goodman OEM cap and O-ring are sized to the exact thread and groove dimensions of the CPC150 service valve. Generic caps with mismatched O-rings are a common source of slow refrigerant leaks. The OEM part guarantees a positive, leak-free seal.
Very easy. Hand-thread the cap onto the service port over its O-ring and snug it with a wrench to the manufacturer's torque. No refrigerant recovery is required to replace the cap itself — a 5-minute job.
