The unit combines a stainless steel mesh filter element with molded nylon ends, providing structural rigidity and dimensional stability under continuous fuel exposure. An oil-resistant O-ring is integrated into the assembly to deliver a leak-tight seal on installation. A cork gasket is also included to seal the pump housing interface. This strainer helps prevent contaminants from reaching internal pump components, supporting consistent burner operation and extending pump service life. It is a direct replacement part suited for licensed oil burner technicians performing routine maintenance or pump service.\u003c\/p\u003e\u003cp\u003eThe 45681 is built for use in residential and light commercial oil burner systems where Suntec fuel unit pumps are installed. Compatible models include Suntec F3 through F20 and R35 series pumps. The strainer fits inline within the fuel supply circuit and is typically serviced during annual burner tune-ups or whenever fuel contamination or flow restriction is suspected. Its compact dimensions make it practical to replace without major disassembly of the burner assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel mesh filter element resists corrosion in fuel oil environments\u003c\/li\u003e\n\u003cli\u003eMolded nylon ends provide strength and dimensional stability\u003c\/li\u003e\n\u003cli\u003eOil-resistant O-ring included for a leak-tight pump seal\u003c\/li\u003e\n\u003cli\u003eCork gasket included for pump housing interface sealing\u003c\/li\u003e\n\u003cli\u003eCompact form factor fits within standard oil burner fuel circuits\u003c\/li\u003e\n\u003cli\u003eDirect OEM-style replacement for listed Suntec pump models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with Suntec F3 through F20 and R35 model fuel unit pumps as stated by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed oil burner technician in accordance with applicable local codes and NFPA 31 guidelines. Shut off fuel supply and de-energize the burner before beginning strainer replacement. Inspect the O-ring and cork gasket seating surfaces for debris or damage before assembly. Do not overtighten the strainer housing, as nylon components can deform under excessive force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: Pump Strainer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Element\u003c\/strong\u003e: Stainless steel mesh\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Material\u003c\/strong\u003e: Molded nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Seals\u003c\/strong\u003e: Oil-resistant O-ring, cork gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CROWN ENGINEERING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 45681\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CROWN ENGINEERING","offers":[{"title":"Default Title","offer_id":51620371661106,"sku":"45681","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01a9ab4514d8e5cdda7da590ab4e05a5.webp?v=1787342439","url":"https:\/\/voomisupply.com\/products\/crown-engineering-45681-pump-strainer-with-o-ring-gasket","provider":"Voomi Supply","version":"1.0","type":"link"}
