The advantages, challenges, and critical aspects to achieving robust seals within hazardous location electrical installations

Explosion-proof conduit fittings, cable glands and connectors require a seal to limit the passage of flames and flammable gases and vapors. This paper will review currently available sealing technologies within the harsh and hazardous electrical market. Advantages and challenges of the various sealing technologies will be identified based on specific chemistries and environmental effects on sealing compound reliability. Additionally, critical installation best practices necessary to reduce risk and achieve robust and safe seals will be discussed.
