DINEX Diesel Particulate Filter Exhaust Gasket for Freightliner/International delivers a precision-engineered sealing solution for DPF and exhaust connections used on Freightliner and International applications. Purpose-built from high-temperature graphite construction and manufactured to OEM form, fit and function, this gasket restores a factory-grade seal where the DPF mates to adjoining exhaust components. A secure seal prevents exhaust gas and soot bypass that can compromise sensor readings, increase visible smoke, and interfere with controlled regeneration events. Installing a new gasket at reassembly eliminates the common failure mode of reused, crushed, or hardened gaskets and reduces the likelihood of repeat service calls for exhaust leaks. The gasket s nominal 5" diameter and 0.83" cross-section match the targeted flange interfaces, enabling straightforward replacement without modification to clamps or mating parts. For fleet operations, the gasket addresses measurable operational problems: it limits exhaust leakage that would otherwise raise backpressure variability and hinder timely passive or active regeneration, helps maintain accurate downstream sensor inputs, and reduces particulate escape that can accelerate nearby component contamination. Because the part is dimensionally consistent with OE interfaces, technicians can complete gasket replacement quickly during DPF or downpipe service, returning units to service faster and reducing vehicle downtime. The product is offered with standard aftermarket warranty coverage and is noted for in-house manufacturing quality control, enabling reliable interchange with OE clamps and gaskets. Recommended industry practice is to fit a new gasket each time the exhaust connection is opened; following that practice with this DINEX gasket helps sustain emission control performance, minimize unscheduled returns, and protect the integrity of downstream emission hardware over successive service events.
