Hoses used in aerospace assemblies are subject to a range of demanding conditions in the field, including extreme temperature variability, high and surging pressure, fire exposure, and impact. The lifespan and durability needs of a particular hose or assembly can differ based on its function and where it’s located within an aircraft, so it’s crucial to ensure each one can withstand the specific rigors of its service environment.

The team at Smithers has the expertise and capabilities needed to conduct testing for various aerospace hoses and assemblies as well as the materials used in hose construction.
