Remember the Past
Since 1998
OuSai seals is a family owned company since 1998. At the beginning of China’s reform and opening up, Mr. Ruijian Lee resigned from his stable job in the government department because of his love for the machinery industry, and started his own business from sealing products. For the past 20 years, he has been working on the domestic market.
With the development of economic globalization, Mr. Ruijian Lee established his own trading company, aiming to take his advantages in this field as the starting point for further development and provide customers with green and durable sealing products and solutions.
Allow customers to receive additional value from Ousai SEALS cooperation.
