HISTORY
About The Hilliard Corporation

Founded in 1905, The Hilliard Corporation has evolved from a one-product business into a special-applications engineering company serving customers worldwide.
Hilliard helps customers evaluate filter cartridges based on the needs of the application, not just a generic test standard. We work to understand the operating environment, performance goals, and system requirements so testing delivers results.
Hilliard products are designed, manufactured, and sold according to our customers’ applications.
As a result, we have a large range of custom-engineered products that can be modified to meet new applications. With a sound understanding of engines and filtration devices, Hilliard engineers design complete systems, including electromechanical interfaces. Hilliard often works with customers to research and test products, acting as a lab for specific applications.
At Hilliard, quality is a way of doing business.
Each of our processes is documented to regulate operation, even on very short production runs. Experienced machinists and code welders work efficiently to keep operating costs low while transforming blueprints into products. Following documented processes, these craftsmen use bar-coded, computerized production controls to guarantee high-quality output. We are an ISO 9001:2015 certified organization.
Our goal is to manufacture products that solve customer problems.
Over the years, we’ve found that the only way to reach that goal is to be flexible. We’re willing to modify existing products, or develop new ones, respond quickly to requests, and take on complicated projects for sophisticated applications. In short, we will work with you to get the job done.
