Based in ChungHua Hsien, Taiwan, and founded by former president Mr. Tson Chi Wu in 1974, Tsuang Hine Oil Seal Corporation, a subsidiary company of ATC Group, is a market leader in providing high quality oil seal solutions. 

With our 320 dedicated employees and over 30 years of solid experience in industrial applications, automotive and motorcycle markets, Tsuang Hine Oil Seal not only has created the well-known trading brands, NTK and PIA, in Taiwan's oil seal industry but has also earned a highly respectful reputation among Asia, Europe, and US markets.

The joint venture with Japan NOK has contributed to the company's success in oil sealing design, testing, manufacturing processes, and most importantly, the rubber compound formulas. Today Tsuang Hine Oil Seal has possessed rubber formulas more than any other oil seal manufacturers in Taiwan which has further consolidated our leading position in providing wide varieties of products and solutions to the end customers.  Within NTK and PIA product ranges, oil seal is just one of our product mainstreams. O-rings, chain tensioners and guides, boots, vibration dampers, manifolds, packings, gears and bushes are among Tsuang Hine Oil Seal's products portfolio.

To the future, Tsuang Hine Oil Seal Corporation will not only continue its leadership in Taiwan’s oil seal market adhering to  its core philosophies of rapid innovation, high quality, and prompt response to the market trend, but also we will be aggressively and ambitiously expanding overseas market share as our corporate goals.
