Goodman B9102097 Liquid Line Cap with O-Ring

The Goodman B9102097 is the OEM liquid line service cap, supplied with its sealing O-ring, for the GPC1336H21A packaged air conditioner. This cap closes the liquid line service port and provides the secondary leak-tight seal that keeps refrigerant contained and contaminants out. A worn or missing O-ring is a frequent source of slow refrigerant loss and capping leaks. Replacing the cap and O-ring together restores a positive, sealed connection.

Specifications

Type: liquid line service port cap
Includes: matched sealing O-ring
Function: secondary refrigerant seal / port protection
Material: brass-style cap with elastomer O-ring
Fit: Goodman GPC1336H21A air conditioner
OEM part number: B9102097

OEM vs. Generic

The OEM B9102097 includes an O-ring sized to Goodman's exact port thread and seat for a dependable refrigerant seal. Generic caps may ship without the correct O-ring or with mismatched threads, risking leaks. The OEM kit is the safe, complete fix.

Installation Difficulty

Easy (2/5). Ensure the service port valve is properly seated, install the O-ring, and hand-tighten the cap plus a snug turn with a wrench. Refrigerant work should be performed by an EPA-certified technician.
