Our History

1963

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.
