The OEM Business Division, headed from our European Office is rapidly distinguishing itself from other Asian Seal Manufacturers, by offering original design capability, and working to the latest ISO-TS16949 Quality Systems. We now supply OEM’s all over the world, ranging from tractors, trailers and motorcycles.
We utilise the latest design, development, test and production equipment, to ensure we offer the most competitive seals, no matter what the quantities.
For more details of our capabilities, please download our latest brochure ”OEM & Aftermarket  Sealing Products”, or request a printed copy. We have started the process of publishing brochures for specific products, starting with the PTFE (Teflon) brochure.
If you wish to discuss or send an enquiry, please contact our Head Office, European Office, or email to info@cho-st.com. We have an “Application Data” form which helps to gather the application data required to recommend or design an appropriate seal.
