WYS (Wonyoung Seal Corp.) – The World Standard in OEM Seals from South Korea
Established on July 17, 1988, the South Korean corporation Wonyoung Seal Corp. (WYS) is one of the leading global leaders in the design and production of high-tech hydraulic and pneumatic seals for industry and heavy construction equipment.
Thanks to its uncompromising quality, WYS is a direct OEM supplier (for initial installation) of global giants in heavy engineering such as Hyundai Heavy Industries and Doosan Infracore. The brand's products are successfully exported to over 40 countries worldwide, covering the most stringent requirements for repair kits for Komatsu, Volvo, Caterpillar, Hitachi, Kobelco, etc.
Key technological advantages of WYS:
Own R&D Center: Established in 2001, the company develops patented, innovative materials, including its own high-performance, heat-resistant polyurethane and polyamide modifications.
Laser precision and CNC technology: Thanks to state-of-the-art production lines using pressing, injection and CNC turning, WYS seals are distinguished by perfectly formed sealing edges and extremely low surface roughness.
Extreme durability: The products are designed to withstand huge hydraulic peaks, peak pressures and extreme temperature amplitudes (from deep winter conditions to high operating temperatures), drastically reducing frictional wear.
Full quality control: Each new profile undergoes internal laboratory tests for hydraulic durability and mechanical load on specialized machines.
International recognition and certificates:
ISO 9001 quality certificate (since 2003).
ISO 14001 Environmental Protection Certificate (since 2005).
Official status for technological innovation Inno-Biz and Main-Biz in South Korea.
