The wrench accommodates filter sizes from 3.125 inches to 4.75 inches (80mm to 120mm), making it suitable across a broad selection of filter housings found in light-duty vehicles, small engines, and equipment serviced in trade and fleet environments. Its self-gripping mechanism increases clamping force as torque is applied, eliminating the need for a separate strap or band tool in most service scenarios. Built from steel, it is suited for professional shop use.\u003c\/p\u003e\u003cp\u003eThis tool is used primarily in automotive, fleet, and equipment service settings where oil filter changes are a routine maintenance task. The self-gripping design provides reliable engagement on smooth or dirty filter housings without requiring additional accessories. It is appropriate for use by automotive technicians, fleet mechanics, and maintenance professionals who encounter a range of filter sizes across different equipment types.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-gripping design increases clamping force with applied torque for secure filter engagement\u003c\/li\u003e\n\u003cli\u003eFits oil filter diameters from 3.125 inches to 4.75 inches (80mm to 120mm)\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in professional shop environments\u003c\/li\u003e\n\u003cli\u003eSingle-piece tool requiring no additional components for operation\u003c\/li\u003e\n\u003cli\u003eCompact profile fits within typical engine bay clearances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with spin-on oil filters ranging from 3.125 inches to 4.75 inches (80mm to 120mm) in outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is used by automotive technicians and fleet mechanics during routine oil filter service. Before use, ensure the engine is off and cooled to a safe handling temperature, and drain the oil as required by the service procedure. Position the wrench around the filter housing and apply steady rotational force — the self-gripping mechanism will engage as torque increases. Follow equipment manufacturer service intervals and disposal guidelines for used oil and filters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Size Range\u003c\/strong\u003e: 3.125 to 4.75 inches (80mm to 120mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.51 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: PROTO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JFF120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51540392182066,"sku":"JFF120","price":131.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83b92be2c8336742096be036ccb175db.jpg?v=1785854046","url":"https:\/\/voomisupply.com\/products\/proto-jff120-steel-oil-filter-wrench-3-125-to-4-75-in","provider":"Voomi Supply","version":"1.0","type":"link"}
