Baldwin CV15012 Premium Heavy-Duty Crankcase Breather ElementProtect your commercial fleet's performance and maintain strict emissions compliance with genuine Baldwin heavy-duty filtration. The CV15012 Crankcase Ventilation (CCV) filter is an essential replacement component for independent diesel shops, transit authorities, and fleet managers servicing medium and heavy-duty trucks powered by Cummins engines.Advanced Emission & Blow-By Control: As heavy-duty diesel engines operate, combustion gases leak past the piston rings and create pressurized blow-by in the crankcase. The Baldwin CV15012 is engineered with advanced, high-efficiency media specifically designed to strip microscopic oil droplets and soot from these gases before they are recirculated. This prevents catastrophic crankcase pressure build-up, stops oil leaks at the engine seals, and ensures your truck passes strict highway emission standards.Exact Fit & Broad Fleet Compatibility: Specifically engineered as a direct replacement for Cummins ISC, ISL (8.9L), and ISX12G engines. These engines are the absolute workhorses of the commercial sector, found across thousands of, and compatible with, Freightliner, Kenworth, Peterbilt, International, and Volvo trucks, as well as Blue Bird, Thomas Built, and New Flyer transit buses. This is a premium direct replacement fit for Cummins 5263190, 4939749, 4937499, Fleetguard CV50628, CV50603, WIX WA11360, and Luber-finer CV9015.Filter Specifications & Included Hardware: Dimensions: 15-7/16" x 6-5/32" x 1-31/32" (392mm x 156.1mm x 50.2mm) Contains: Integral By-Pass Valve Included Hardware: (1) Attached Gasket & (2) Attached O-Rings
