Flex-a-Seal, Inc. is a privately held company started in 1983. It was started in Ormand Beach, Florida primarily as a welded metal bellows mechanical seal manufacturer with only 3 employees and small customer base scattered throughout the United States.
In the 20 years since its inception, Flex-A-Seal has evolved in a number of directions. We are a fully integrated seal manufacturer that conceptualizes, designs, manufactures, markets, sells, services and repairs our complete line of mechanical seals and related devices worldwide.

Hermetic Bellows Devices - Flex-A-Seal has manufactured the highest quality welded bellows for mechanical sealing applications for over 20 years; the step into hermetic bellows vacuum, semiconductor, pharmaceutical, cryogenics and hazardous material handling applications was a logical and strategic move.

Seal repair - Flex-A-Seal has diversified into other related areas such as seal repair of our own seals as well as any competitor seal, designing hermetic bellows devices for the semiconductor and vacuum industry.
