OEM Goodman Liquid Line Cap w/ O-Ring for WGPH4560AMAB — B9102097

Goodman B9102097 Liquid Line Cap with O-Ring

The B9102097 is a genuine OEM liquid line service cap with an integrated O-ring for the Goodman WGPH4560AMAB packaged air conditioner. This cap threads onto the liquid line service port and provides the system's secondary leak barrier — the O-ring seals against the port face so refrigerant cannot weep past the Schrader core over time. A missing cap or a dried, cracked O-ring is a common slow-leak source that quietly reduces system charge and cooling capacity.

OEM vs. Generic

OEM caps match the exact thread pitch and O-ring durometer specified for the WGPH4560AMAB port, ensuring a positive seal that holds high-side pressure. Generic caps may use the wrong O-ring material or thread fit, allowing slow leaks. Always replace the cap and O-ring together when servicing the port.

Install Difficulty

Easy. Confirm the Schrader core is sealing, seat the O-ring, and hand-tighten the cap snugly (do not overtighten). No refrigerant recovery is required for a routine cap-and-O-ring replacement.
