Senior Flexonics’ reputation for excellence is based on its commitment to continuous business improvement and customer service.  We strive to continually improve the operation of our business so that we can serve our customers better.

A History of Innovation

In 1902 James Fentress founded what was to become the Senior Flexonics that you now know. From humble beginnings as a single product manufacturer the company grew into an international organization over the next century. It was a time of innovation and achievement in which the company diversified and expanded to become the great organization it is today. Here is a small list of industry “firsts” that were accomplished with our customers:


  • First to make stainless steel hose
  • First to make stainless steel bellows
  • First to make multi-ply stainless steel bellows for high pressure
  • First to make high-strength, butt-welded thin wall stainless steel ducting
  • First to make deposition-formed, one piece, thin wall duct components such as elbows, tees, manifolds, and transition pieces that replaced casting and half shells welded together
  • First to furnish insulated ducting sheathed and sealed
  • First to completely design, manufacture and qualification test an entire high temperature aircraft duct system for heating, ventilating, refrigeration, anti-icing and boundary layer control systems
  • First supplier to install complete pneumatic duct flow facilities for environmental testing of components and complete aircraft ducting systems
