This cap threads onto the liquid-side service port and is the system's secondary refrigerant seal — its bonded O-ring prevents slow refrigerant loss at the Schrader valve and keeps moisture and debris out of the sealed system. A missing or dry-rotted cap is a common, overlooked cause of gradual charge loss.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B9102097\u003c\/li\u003e\n\u003cli\u003ePart Type: Liquid line service cap with sealing O-ring\u003c\/li\u003e\n\u003cli\u003eCompatible Model: WPC4430AHAB\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003cli\u003eEquipment: Air Conditioner\u003c\/li\u003e\n\u003cli\u003eIncludes: Cap + replacement O-ring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine OEM\u003c\/strong\u003e cap arrives with the correct durometer O-ring already matched to the port — no guessing on seal size.
