This brass cap threads onto the liquid-line service valve and, together with its captive O-ring, provides the secondary leak-tight seal that backs up the valve core. Because it is a sealing component on the high-pressure liquid line, a worn or missing O-ring cap is a common slow-leak culprit that drains charge over a season.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B9102097\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e WGPH4543AMAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Service cap + O-ring seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Leak-tight closure for the liquid-line service port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The OEM cap arrives with the correct durometer O-ring and matching thread pitch, so it seals on the first turn. Generic caps frequently ship without an O-ring or with the wrong size, leaving you chasing a phantom refrigerant leak. The bundled seal makes the OEM part the reliable pick.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall Difficulty:\u003c\/strong\u003e Easy (1 of 5). With the system at rest, thread the cap on hand-tight plus a quarter turn with a wrench. No refrigerant recovery is needed to swap the cap itself — but always wear eye protection when working near pressurized lines.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Direct Replacement","offer_id":63032353685875,"sku":"B9102097-GEN","price":8.95,"currency_code":"USD","in_stock":true},{"title":"OEM","offer_id":63048269594995,"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-coupling-B9102097_9cd35dbb-4a25-43ee-a42e-702769d3ce44.jpg?v=1782949134","url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-liquid-line-cap-with-o-ring-for-wgph4543amaa-b9102097","provider":"National HVAC Parts","version":"1.0","type":"link"}
