Flexial Corporation is a leading manufacturer of welded metal bellows for wireline, drilling, and lift applications. Flexial's welded metal bellows are used as protective covers for quartz pressure sensors, for fluid density measurement in welded bellows gradiomanometers, and for high pressure bellows gas lift seals.

The Flexial Reactive Seal, developed under contract from DARPA and the EPA, is a new concept that ensures zero fugitive emissions, while allowing the freest possible stem motion.
