Understanding O-ring Complexity in the Aerospace Industry


O-rings are a ubiquitous, uncomplicated sealing solution for virtually millions of products. They seal out moisture and environmental contaminants, separate surfaces to mitigate friction, and keep in essential fluids. Despite their seeming simplicity, however, O-rings used in aerospace applications take on an unexpected level of material and performance complexity when engineering and design standards and industry regulations are factored into purchasing decisions.

The number of O-rings found on an average commercial jetliner reaches into the thousands, and each must compensate for different environmental conditions including high and low pressure, aggressive lubricants and fluids, extreme heat and cold, industrial performance requirements, and even challenging installation procedures. With no one-size-fits-all O-ring solution for the aerospace industry, manufacturers must rely on the material, testing, and industry expertise of their suppliers to help identify the best seals for every unique use.

This 60-minute Webinar reviews the challenges associated with O-rings used in the aerospace industry and provides guidance about the critical factors that must be considered in every sourcing decision.

An audience Q&A follows the technical presentation.
