What is the main purpose of seals or sealoffs in conduit runs?

The primary purpose of seals or seal-offs in conduit runs is to prevent the passage of gases, vapors, or flames. This is crucial for ensuring safety in electrical installations, especially when conduits are used in environments where flammable materials or hazardous gases may be present. Seal-offs create a barrier that can effectively contain any potential hazards, minimizing the risk of explosion or fire that can occur if these substances are allowed to travel through the conduit system.

By employing seals in conduit runs, electrical installations are better protected against environmental hazards, maintaining safety and compliance with regulations in areas such as industrial settings, hazardous locations, and areas requiring enhanced fire safety. This function is vital for protecting both the equipment within the conduit and the surrounding areas from accidental ignition or contamination.
