Jinwoseal, a leading global sealing technology supplier, today officially launched a full range of customizable DPF sealing gaskets designed for the harsh working conditions of diesel vehicle exhaust treatment systems (DPF). The product uses graphite and stainless steel composite materials and a modular structure, marking a leapfrog upgrade from "standard parts adaptation" to "precise scene matching" in the field of high-temperature sealing.

Industry pain points drive innovation: let sealing performance match the speed of DPF evolution

With the global implementation of the National VI B/Euro VII emission regulations, the peak operating temperature of DPF has exceeded 700℃. Traditional sealing gaskets generally face three major challenges:


High temperature oxidation: Ordinary graphite expands out of control above 600°C, resulting in seal failure


Vibration fatigue: Frequent start-stop of commercial vehicles causes stress cracking of metal gaskets


Adaptation rigidity: Non-standard DPF models require repeated mold modifications, delaying project cycles


Jinwoseal's new products use material innovation + digital customization dual engines to solve industry problems in a targeted manner:


Multi-layer composite technology:


Flexible graphite layer (purity ≥99.9%) provides high-temperature self-compensating seals


316 L stainless steel skeleton (thickness 0.1-2.0mm optional) resists mechanical vibration


Nano ceramic coating (optional) blocks acidic exhaust corrosion


48-hour fast customization:


Supports full-size coverage of 20-600mm diameter


Can be adapted to mainstream DPF models such as Cummins, Bosch, and Faurecia


Laser cutting process achieves ±0.05mm accuracy (80% higher than traditional mold accuracy)



Measured data confirms technological breakthroughs

In a 1500-hour simulation test in a third-party laboratory, Jinwoseal DPF gaskets show excellent performance.


"This product shortened the development cycle of our non-standard DPF project by 3 weeks." - Feedback from the purchasing director of a European commercial vehicle manufacturer in a blind test.
