OEM Goodman Liquid Line Cap w/ O-Ring for WGPH4549AMAA — B9102097

The Goodman B9102097 Liquid Line Cap with O-Ring is the genuine OEM service-port cap that seals the liquid line connection on WGPH4549AMAA packaged units. This cap is the secondary leak barrier on the service valve — its captive O-ring blocks the slow refrigerant seepage that a missing or hardened cap allows. A lost cap, cracked threads, or a dried-out O-ring is a frequent cause of gradual refrigerant loss and reduced cooling capacity, so replacing it is cheap insurance for the sealed system.

OEM vs. Generic

The genuine Goodman cap ships with the correct thread pitch and an O-ring rated for the system's refrigerant and operating pressures. Generic caps may use an incompatible elastomer that swells or cracks, defeating the seal. OEM ensures a true leak-free closure.

Installation Difficulty

Easy — Hand-thread the cap onto the service port over a lightly seated O-ring and snug it with a wrench; do not overtighten. A 5-minute task. Note: the cap seals an already-charged port and is not a substitute for proper sealed-system service.
