The genuine Goodman part is molded to the exact port diameter and rated for the combustion-area heat. Generic rubber grommets can shrink, harden, or deform near the burner, breaking the seal and triggering pressure-switch or flame-sensing faults. The OEM bushing guarantees a proper, lasting seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Easy (1\/5). With power and gas off, pop out the old bushing, clean the port opening, and press the new grommet into place, then reseat the view-port lens. This is a two-minute repair requiring no tools. It is often replaced alongside a burner or heat-exchanger service to restore a clean combustion seal.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058243387763,"sku":"GOODMAN-14482","price":8.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-sight-view-port-bushing-for-wgfm28115v5cxaa-b1392139","provider":"National HVAC Parts","version":"1.0","type":"link"}
