DINEX Stainless Steel Diesel Particulate Filter Clamp for Cummins / Paccar / Volvo 15.51in is a heavy-duty exhaust clamp engineered to secure diesel particulate filter (DPF) and exhaust system joints on medium- and heavy-duty powertrains. Constructed from stainless steel and sized with a nominal 15.51 in diameter and approximately 1 in profile height, this clamp provides a robust, corrosion-resistant fastening point designed for high-temperature exhaust environments. The clamp directly replaces common OE clamp designs used on Cummins, Paccar and Volvo applications and is produced to match the form-and-fit expectations of original equipment installations. In operation, it addresses the frequent fleet problem of exhaust leaks and loose DPF connections that cause soot bypass, reduced aftertreatment efficiency, and soot accumulation on surrounding components. A properly secured DPF connection maintains exhaust backpressure within expected ranges and limits particulate escape, which helps preserve DPF regeneration performance and reduces unscheduled maintenance events. For fleet maintenance planners, the clamp delivers measurable value through extended joint service life, fewer clamp replacements, and reduced labor time compared with repeatedly reworking poorly fitting or corroded clamps. The unit weight is approximately 2.56 lb, and dimensional data support quick assessment for inventory and stocking decisions. Built from stainless alloy for enhanced longevity in corrosive and high-heat exposures, the clamp supports consistent sealing performance across duty cycles. The design also simplifies installation and removal during scheduled DPF service, enabling faster turn-around during filter inspections or replacement. Specified for EPA10 emission norm applications, this clamp is intended for use where reliable exhaust system fasteners are required to maintain aftertreatment integrity and minimize downtime across heavy-duty fleet operations.
