Dinex Diesel Particulate Filter for Mack and Volvo Engines DPF EPA10 Stainless Steel 12.6" x 13.31" is an aftermarket aftertreatment component engineered to manage particulate emissions in heavy-duty diesel exhaust systems used on specified Mack and Volvo platforms. This Dinex DPF is manufactured to match OE fit and function where listed, and it is produced with a stainless steel housing and high-efficiency filtration substrate specified for EPA10 emission norms. The unit’s nominal external diameter measures approximately 12.60 inches with an overall length near 13.31 inches and a net weight in the mid-60 lb range, enabling direct replacement in applications that reference the listed OE part numbers and cross-references. Several supplier kits are supplied complete with installation gaskets and clamps to simplify field replacement and reduce vehicle downtime by minimizing parts gaps during service. The Dinex DPF is offered with a multi-year warranty in certain markets, reflecting manufacturer confidence in component durability and coating processes intended for high-temperature exhaust environments. For fleet operations, the Dinex DPF addresses the operational problem of soot accumulation and particulate emissions that degrade aftertreatment effectiveness and increase regeneration frequency. By restoring filtration capacity and maintaining target backpressure characteristics consistent with OE specifications, the DPF helps normalize regeneration intervals and reduces the risk of forced regenerations or engine derates caused by excessive soot loading. Replacement with a properly specified Dinex unit supports consistent engine performance, predictable service intervals, and helps fleets meet regulatory emissions requirements for EPA10-class engines. Purchase options are offered with and without accessory clamps and gaskets; check the selected kit contents before installation to ensure a complete replacement.
