Grotenrath was established in 1939 by William P. Grotenrath (right), his goal was to supply quality products at a fair price and provide fine service to all customers.

In 1979 Kirk DuBois, his grandson, inherited the business and his goal remained the same as that of his grandfather. Now, sixty years later, Grotenrath has achieved that goal, by concentrating on the quality of products and services we provide to all our customers in North America.

Grotenrath sells and distributes high quality "O" Rings for hydraulic and pneumatic applications. From our extensive inventory we can fill orders for seals in both inches and metric dimensions. In addition to our standard sizes, we can provide non-standard "O" Rings from stock and specially manufactured seals for unique customer requirements.

Grotenrath also stocks several other lines of popular sealing products including molded, leather, plastic, and urethane seals.

Grotenrath is dedicated to both our industrial and military needs. Our fine products are supported by our fine service, which includes fast delivery and a fair price.
