Code of Conduct


Jonal Laboratories began in 1965 when John Nemeth made a decision to develop a company that could manufacture non-metallic rubber-based parts for the aerospace industry. His innovative approach and sincere desire to control costs has helped Jonal Labs gain a competitive advantage in the industry. To this day the company remains a family owned institution with Marc Nemeth at its helm.

Over the years, Jonal Laboratories has grown from a job shop to a custom manufacturer with design assistance supplying a wide range of elastomeric products for the aerospace, military, and industrial markets. Products range from standard o-rings to custom designed complex molded shapes, fabric reinforced seals, thin walled diaphragms, aerodynamic and platform seals, rubber-to-metal bonding, silicone extrusions, and EMI/RFI shielding products.

In 1997, Jonal was recognized as a finalist in the Nozko Family Business Leadership Awards. The criterion for this award was based on the success of a business and its contribution to industry and community. Today, as in 1997, Jonal Labs proudly continues to provide consistent civic and industrial leadership. Jonal believes that the company owes something to the people in the community where we work.
