Esterline Power Systems can provide:

  • Lower cost
  • Lighter weight
  • More reliable solutions

Our success comes from our leading-edge manufacturing techniques, such as laser welding and strenuous testing at every stage of production. Our goal is a zero failure rate; perfect reliability means a relentless reach for impurities, and meticulous adjustment of the components. Our products do not leave the clean room until they are safely sealed inside their casings. They will, after all be facing severe conditions including: vibration, jolting, dampness, pollution, and extreme temperatures and pressures.
