Dust Seal Solutions by Polypac

Why Dust Seals Matter

Dust Seal performance directly impacts equipment reliability. Polypac's Dust Seal designs prevent particulate ingress, reduce wear on bearings and actuators, and extend maintenance intervals. Engineered for low friction and long service life, our seals form the first line of defense in hydraulic systems, construction equipment, and industrial machinery.

Advanced Materials & Expertise

We manufacture Dust Seals using a wide range of materials tailored to application demands. Leveraging our heritage in filled PTFE (bronze-filled, carbon-filled, graphite, MoS₂, and glass-filled) and elastomers (NBR, FKM, silicone, EPDM, FFKM), Polypac optimizes resilience against abrasion, temperature, and chemical attack. Our material development teams work with universities and research institutes to validate formulations for special working conditions.

Custom Design & Manufacturing

Founded in 2008, Polypac combines decades of seal expertise with one of China’s largest dedicated production facilities. Our custom rubber ring and O-ring factory spans over 10,000 m² with an 8,000 m² workshop equipped with state-of-the-art production and testing equipment. We deliver bespoke Dust Seal geometries, lip profiles, and compound selections to meet unique installation and performance criteria.

Applications & Industry Use

Polypac Dust Seals serve a broad range of industries: hydraulic cylinders, mobile equipment, agricultural machinery, mining, and heavy-duty OEMs. Typical benefits include enhanced dust exclusion, improved contamination control, and reduced lifecycle costs. We design for both static and dynamic sealing scenarios, considering shaft speeds, pressures, and environmental exposure.

Quality Assurance & Testing

Every Dust Seal undergoes rigorous testing—dimensional inspection, material characterization, and simulated wear trials—to ensure consistent performance. Our QA systems and traceability measures support high-volume production runs as well as small-batch customization.
