market leader in complex and tight tolerance sealing solutions

Sealing Solutions

Aero engine efficiency is becoming an increasingly important factor for the aviation industry for both operational costs as well as reducing greenhouse gas emissions. Mechanical seals ensure minimization of air leakage between rotating blades and stationary parts.


Extremely tight tolerances are necessary to ensure proper sealing. We offer all manufacturing processes in-house that will meet the most stringent specifications and requirements for a wide range of seals, including honeycomb, abradable and labyrinth seals. Special processes include:

  • Electrical Discharge Machining (EDM)
  • Vacuum Brazing
  • Spot welding

With an extensive history in repair development for seals and other sheet metal fabrications, Senior Aerospace Bosman also offers repair development to improve cost effectiveness for its customers.
