OEM Goodman Liquid Line Cap w/ O-Ring for WPC4436AHAB — B9102097

The Goodman B9102097 Liquid Line Cap with O-Ring is a genuine OEM service-port seal for the Goodman WPC4436AHAB packaged air conditioner. This cap threads onto the liquid line service valve and, together with its captive O-ring, forms the secondary leak barrier that keeps R-410A refrigerant sealed inside the system between service visits. A missing or cracked cap — or a flattened O-ring — lets refrigerant weep past the valve core and invites moisture and contaminants into the line set.

OEM vs. Generic

The genuine OEM cap ships with the correct durometer O-ring and exact thread pitch for the Goodman liquid valve. Generic caps frequently use the wrong O-ring size, which deforms on the first tightening and fails to seal — the very problem you are trying to fix. OEM ensures a positive, refrigerant-tight seal.

Installation Difficulty

Very easy (1 of 5). Hand-thread the cap onto the liquid line valve and snug with a wrench until the O-ring just compresses. No refrigerant recovery or evacuation required. A 2-minute job that protects your charge and your line set.
