It threads onto the liquid line service valve and, together with its captive O-ring, forms a leak-tight seal that protects the refrigerant charge between service visits. A worn, missing, or cross-threaded cap is one of the most common sources of slow refrigerant loss, so replacing it with the correct OEM part keeps your system holding charge and running efficiently.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGoodman OEM part number: B9102097\u003c\/li\u003e\n\u003cli\u003eType: Liquid line service cap with sealing O-ring\u003c\/li\u003e\n\u003cli\u003eFits: WPC4336AHAA package air conditioner\u003c\/li\u003e\n\u003cli\u003eFunction: Seals refrigerant access\/service port\u003c\/li\u003e\n\u003cli\u003eIncludes: Cap and O-ring as a matched set\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM cap ships with the factory-spec O-ring durometer and thread pitch, so it seats fully and holds pressure the first time. Generic caps are lower cost but frequently use a slightly mismatched O-ring that weeps under high-side pressure — fine for a temporary fix, less ideal for a sealed refrigerant circuit. For a part this inexpensive, OEM is the safe choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (DIY-friendly).\u003c\/strong\u003e Hand-thread onto the service port and snug with a wrench — no refrigerant handling required for the cap itself.
