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.

The company moved to an old battery manufacturing plant on Neoga Street in Depew, New York to keep up with expanding business volume. Terry sold products by day and worked on quotes and paperwork by night while Marian took care of invoices, billing materials and other office functions.

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.

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

Company sales exceeded $36.5 million which caused Sealing Devices to purchase the adjacent five-acre property at 4380 Walden Ave.

Sealing Devices celebrated 45 years of business.

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.
