Established in Taiwan in 1994, WDH Industrial has built a 30-year track record in sealing technology R&D and manufacturing, with an enduring focus on solving sealing pain points for agricultural and heavy industrial machinery.
As the exclusive official operator of the WDH seal brand, Suzhou Wude Machinery Accessories Co., Ltd. runs our full-scale production facility in Kunshan, China. We combine Taiwan-originated design expertise and quality standards with localized large-scale production capacity, delivering dependable sealing products to customers across Southeast Asia, Europe, the Americas and beyond.
WDH focuses on high-performance radial shaft seals, heavy-duty cassette mud seals and custom engineered rubber sealing solutions built for extreme operating environments.
Our core product range includes standard skeleton oil seals and application-specific mud seals, fully compatible with mainstream agricultural machinery platforms such as Kubota and Yanmar harvesters and tractors. Available in NBR, HNBR, FKM and ACM materials, our seals perform reliably across a temperature range of -55°C to 250°C, providing long-term leak protection even in muddy water, high temperature and heavy load working conditions.
Quality is the foundation of our brand. We strictly implement the IATF 16949 automotive-grade quality management system across every stage of production, from raw material compounding and mold fabrication to vulcanization, precision inspection and performance testing.
Our Kunshan production base is equipped with automated manufacturing lines and a complete set of precision testing equipment, operated by a team of senior sealing engineers with decades of industry experience. We keep over 10,000 standard seal sizes in ready stock, and offer rapid tooling services for non-standard custom orders to address diverse and urgent customer needs.
