Terry Galanis Sr. launched Sealing Devices from his home in Alden, New York with an investment of $157 in Parker O-Rings. His wife Marian would answer the phone and his children would count and bag o-rings. Terry’s vision was to provide customers with quality parts, reliable service and fair prices.

Continuous growth sparks the company’s next move to Lancaster, New York with the purchase of a 7,500 square foot building at 4375 Walden Ave.

Sealing Devices topped $1 million in total sales and thus purchased an additional 5,000 square feet to add to the existing Walden Avenue plant.

Terry Galanis Jr. joined the company.

The company surpassed sales of $3.5 million and outgrew the existing office space. The Galanis family then purchased six acres of land across the street at 4400 Walden Ave. The $1.3 million building included 34,000 square feet of office space and provided a state-of-the-art fabrication and distribution center.

Terry Jr. is appointed President and CEO.

Twenty-eight thousand square foot addition made to the location at 4400 Walden Ave. after sales topped $17 million.

Thirty-two thousand square foot expansion of combined office, meeting and manufacturing areas is completed.

Corporate headquarters and manufacturing facilities remain in Lancaster. The sales branches in Erie, Rochester and Syracuse continue to flourish with local, national and international customers. Sealing Devices has provided products to customers in Puerto Rico, Mexico, Brazil, Great Britain, Ireland and Australia.
