With an outside diameter of 11.719 inches and an overall length of 23.313 inches, this element fits large-bore filter housings common in construction, agricultural, and industrial equipment. The molded urethane end seals the element securely in the housing, preventing unfiltered air bypass. Weighing 8.6 pounds, this is a robust, direct-service replacement intended for licensed technicians and fleet maintenance professionals performing scheduled air system service.\u003c\/p\u003e\n\u003cp\u003eThis filter element is suited for heavy-duty off-highway applications including construction machinery, agricultural equipment, and industrial power units that rely on large-format radial filter housings. It is a cost-effective service replacement that simplifies scheduled maintenance intervals. Cross-reference compatibility with Caterpillar 2453818, Donaldson P782106, Hastings AF2460, and Wix 549811 makes it a viable drop-in option when sourcing replacements across multiple equipment brands on a job site or in a fleet shop.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRadial filter geometry with 11.719 inches outside diameter and 23.313 inches overall length for large-format housings\u003c\/li\u003e\n  \u003cli\u003eMolded urethane end compound forms a secure seal against the housing to prevent air bypass\u003c\/li\u003e\n  \u003cli\u003eProtects heavy-duty engine components by capturing airborne dirt and contaminants before they enter the intake\u003c\/li\u003e\n  \u003cli\u003eCross-references to Caterpillar 2453818, Donaldson P782106, Hastings AF2460, and Wix 549811\u003c\/li\u003e\n  \u003cli\u003eCost-effective OEM-style replacement designed to simplify scheduled service intervals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCross-references to Caterpillar 2453818, Donaldson P782106, Hastings AF2460, and Wix 549811.
