It threads onto the liquid line service port and, together with its captive O-ring, forms a leak-tight seal that protects the refrigerant charge and keeps moisture and contaminants out of the sealed system. A worn, missing, or cross-threaded cap is one of the most overlooked sources of slow refrigerant loss, so installing the correct OEM cap is cheap insurance for the whole system.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Liquid line service cap with captive O-ring\u003c\/li\u003e\n\u003cli\u003eOEM part number: B9102097\u003c\/li\u003e\n\u003cli\u003eCompatible model: WGPH4549AMAB\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003cli\u003eApplication: Air conditioner \/ packaged unit refrigerant line\u003c\/li\u003e\n\u003cli\u003eMaterial: Plated brass cap with synthetic O-ring seal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman OEM cap arrives with the correct thread pitch and a factory-spec O-ring that seats fully on the first turn. Generic caps are usually a few cents cheaper but frequently ship without an O-ring or with an undersized one, which can lead to weeping joints and repeat service calls. For a sealing component on a pressurized refrigerant circuit, the OEM part is the safer choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e Hand-thread the cap onto the service port and snug it lightly — no tools or refrigerant handling required for the cap itself.
