The Goodman B9102097 Liquid Line Cap with O-Ring is the OEM sealing cap for the liquid-line service port on the GPC1348H21A packaged air conditioner. The cap is a secondary leak barrier: with its captive O-ring it seals the Schrader port so refrigerant cannot weep past the valve core over time. A missing or O-ring-less cap is a frequent, easily-overlooked source of slow refrigerant loss.

Specifications

Application: liquid line / service valve port
Includes integrated O-ring seal
Brass/steel cap with factory thread pitch
OEM Part Number: B9102097
Fits: Goodman GPC1348H21A and compatible packaged units

OEM vs. Generic

The OEM B9102097 ships with the correct O-ring already fitted and the exact thread match for the Goodman service valve. Generic caps are often O-ring-free and rely on metal-to-metal sealing, which does not reliably hold against refrigerant pressure on a vibrating unit.

Installation Difficulty

Easy — thread the cap onto the service port by hand and snug with a wrench. Under 5 minutes; verify the O-ring is seated before tightening. No system evacuation required for cap-only replacement.
