This grommet creates a sealed pipe entry point where a 4-inch hub penetrates the basin wall, preventing infiltration and maintaining system integrity. Constructed from rubber, it provides flexible, durable performance under typical sewage basin conditions. Plumbers and drain-waste-vent installers use this fitting to properly terminate hub connections at the basin, keeping the assembly watertight and code-compliant. The flanged design holds the grommet securely in place during and after installation.\u003c\/p\u003e\n\u003cp\u003eThis hub grommet is suited for residential and light commercial sewage pump basin installations where a 4-inch pipe entry point requires a sealed, flexible connection. It is installed at the point where a hub-end pipe passes through the basin wall, accommodating minor misalignment and vibration while maintaining a secure seal. Sewage ejector pump systems commonly require this type of fitting when setting up basin penetrations during new construction or replacement service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlanged design holds grommet securely against the basin wall\u003c\/li\u003e\n  \u003cli\u003eRubber construction provides flexibility and resistance to typical sewage basin environments\u003c\/li\u003e\n  \u003cli\u003eSized for 4-inch hub pipe connections\u003c\/li\u003e\n  \u003cli\u003eCompatible with pump sewage basin installations\u003c\/li\u003e\n  \u003cli\u003eHelps maintain a watertight seal at pipe entry points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with pump sewage basins requiring a 4-inch hub grommet penetration seal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber during sewage ejector system setup or basin service. Before installing or replacing this grommet, shut off power to the sewage pump and ensure the basin is accessible and safe to work in. Seat the flanged grommet fully against the basin wall before inserting the pipe to ensure a proper seal. Follow local plumbing codes and IPC guidelines for sewage basin penetration requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Grommet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Flanged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Rubber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Pump Sewage Basins\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ZOELLER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZOEL-018228\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ZOELLER","offers":[{"title":"Default Title","offer_id":51383781130546,"sku":"ZOEL-018228","price":27.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670193.jpg?v=1782607276","url":"https:\/\/voomisupply.com\/products\/zoeller-zoel-018228-hub-grommet-flanged-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
