What is the primary purpose of a seal fitting in conduit installations?

The primary purpose of a seal fitting in conduit installations is to minimize the passage of gases, vapors, and flames. Seal fittings are essential components used in certain conduit systems to ensure that any potentially hazardous or harmful substances do not escape into the surrounding environment. This is particularly important in locations where there may be flammable or noxious gases, as seal fittings help create a secure barrier.

Furthermore, these fittings are designed to prevent the spread of fire and smoke between different areas, aiding in fire safety and compliance with various codes and regulations. The application of seal fittings is critical in applications such as hazardous locations or industrial settings where safety is a top priority.

While enhancing appearance, minimizing thermal expansion, and allowing for easier access may have their own benefits in certain contexts, they do not capture the core functionality for which seal fittings are primarily designed. The central aim is always focused on safety and containment, making the prevention of gaseous or flame passage the most critical aspect of their function.
