About Us



With a clear vision set forth by founder Thomas Roake in 1977, we have grown to become a world leader in the manufacturing of precision hydraulic manifolds. Ever since our first manifolds hit the market, we have been considered the "gold standard" for these products and we continue to expand our capabilities to meet the needs of our customers.

Continuous improvement in equipment and our people has helped us to achieve an impressive record of growth and increased sales. We currently employ over 100 associates at our nearly 100,000 sq. ft. suburban Chicago headquarters. Our skilled technicians work exclusively on Mazak machines, and all Tomenson associates participate in extensive and ongoing training.

Commitment to Quality


As a quality-driven, customer-focused company, we rely on our experience and expansive knowledge in the manufacturing of hydraulic manifold blocks to ensure customers get their product in time and to their specifications. All employees are trained from the beginning that quality is of the upmost importance when creating our manifolds.
