Flowmark/Hightech Filters was established in 1982 in Billings, Montana. The company steadily became an industrial sealing business along with a complete filtration division. Flowmark/Hightech began in an office at its founders home with filters being stocked in the garage. With the help of many along the way, the company has continued to grow. Due to growth, the company has relocated a couple times until settling into our current location, a 24,000 square foot building on the West End of Billings. In 2004, Flowmark/Hightech’s founder retired and the company was acquired by Charles Duke, owner of Montana Seals and Packings, another trusted name in the sealing industry. This change in ownership brought on an exponential growth in company sales and success. We are proud to say that we still carry on our trusted name and excellent customer support.
