Website Sealing Devices

Beginning with an investment of $157 in Parker O-rings, and the ideals of starting a “small business that would employ a few good people and make some money,” Terry Galanis, Sr. launched Sealing Devices Inc. from his Alden, NY home in July of 1963. The elder Galanis started the Company with a vision of providing customers with quality parts, reliable service and fair prices. The Company was a family affair from the beginning with his wife Marian answering the phone, and the children (including current President Terry, Jr.) involved in counting and bagging O-rings in their home.
