This cap threads onto the liquid line service port and forms the secondary seal that prevents refrigerant from leaking past the Schrader valve. A missing, cross-threaded, or dry-rotted cap is a common cause of slow refrigerant loss — and a slow leak means weak cooling and eventual compressor damage.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B9102097\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003cli\u003eFits Model: WPC4348AHBA\u003c\/li\u003e\n\u003cli\u003eIncludes: Service cap + sealing O-ring\u003c\/li\u003e\n\u003cli\u003eFunction: Liquid line service port seal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman cap arrives with the correctly sized, refrigerant-rated O-ring already matched to the port threads. Generic caps may use the wrong O-ring durometer or thread pitch, which won't seal reliably under system pressure. Because this part directly protects your refrigerant charge, the OEM seal is worth the small premium.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2 of 5).\u003c\/strong\u003e With the system off, seat the O-ring and hand-thread the cap onto the service port, then snug it with a wrench — do not over-tighten. If the port was leaking, have refrigerant levels checked afterward by a licensed technician, as handling refrigerant requires EPA certification.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Direct Replacement","offer_id":63032358306163,"sku":"B9102097-GEN","price":8.95,"currency_code":"USD","in_stock":true},{"title":"OEM","offer_id":63048266711411,"sku":"B9102097","price":11.63,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-fitting-cap-B9102097.jpg?v=1782949048","url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-liquid-line-cap-w-o-ring-for-wpc4348ahba-b9102097","provider":"National HVAC Parts","version":"1.0","type":"link"}
