The Goodman B9102097 Liquid Line Cap with O-Ring is the genuine OEM service-port seal for your WPC4448AHAB air conditioner. This cap threads onto the liquid line service valve and uses an integrated O-ring to provide a secondary, leak-tight seal that protects the refrigerant charge and keeps moisture and debris out of the system. Missing or damaged caps are a frequent cause of slow refrigerant loss — installing a fresh OEM cap restores a proper seal.

Specifications

OEM Part Number: B9102097
Part Type: Liquid Line Service Cap (includes O-Ring)
Fits Model: WPC4448AHAB
Seal: Captive O-ring for secondary leak protection
Material: Brass/steel cap with elastomer O-ring

OEM vs. Generic

The genuine Goodman OEM cap is sized to the exact valve thread and ships with the correct O-ring durometer for refrigerant service. Generic caps may omit the O-ring or use an incompatible seal that hardens and leaks.

Install Difficulty

Very Easy (1/5). Hand-thread the cap onto the liquid line service port and snug with a wrench — no refrigerant recovery or tools beyond an adjustable wrench needed. Do not over-tighten the O-ring seat.
