Ergoseal Business Succession Leads to Rapid Growth

Ergoseal, Inc. has dramatically expanded its product line and manufacturing capabilities through the acquisition of two companies.

The 25-year-old designer and manufacturer of precision-engineered mechanical seals is now in the unique position to provide the widest selection of seals in the industry, including lip, mechanical, and non-contacting seals for industrial, aerospace, and sanitary applications. Ergoseal is now one of the few companies in the industry to have an automated visual measuring system, which is critical for the inspection of elastomeric and rubber products.

On June 27, Ergoseal acquired California-based Norman Technology, a manufacturer of a wide variety of mechanical seals, lip seals, and rubber components. The following month, on July 16, the acquisition of Sieber Tooling Solutions brought advanced manufacturing capabilities to Ergoseal, including added machining capacity plus precision grinding for various metal forging industries. Sieber, located adjacent to Ergoseal’s headquarters, will continue to operate as a division of Ergoseal; Aug. 20 marked the date of the completed transition.

Besides expanding Ergoseal’s product line and services, the rapid growth marks a pivotal milestone for the family-owned company. Tom Hilaris became President and CEO of Ergoseal on May 1, taking the reins from his father, Ergoseal founder John Hilaris. Father and son had already been planning and positioning for growth by fine-tuning processes and procedures with an eye toward building capacity. Just three months after becoming President, Tom sealed the two deals—the first-ever acquisitions for Ergoseal.

“Ergoseal, Norman, and Sieber customers now have a sole supplier they can turn to for a range of custom and industry-standard sealing applications, along with a full complement of manufacturing services,” said Tom Hilaris. “What hasn’t changed is our commitment to develop and deliver precision seals tailored to the needs of our customers.”

With many OEMs consolidating suppliers, Ergoseal is now ideally positioned to fulfill a wider range of customer needs.
