What does it mean for a fitting to be "weatherproof"?

A fitting being described as "weatherproof" means that it is designed to withstand exposure to outdoor conditions without deteriorating or failing. This includes being resistant to moisture, UV radiation, temperature fluctuations, and other environmental factors that can affect materials when used outside. Weatherproof fittings are essential in applications where electrical components are exposed to elements, ensuring safety and functionality over time.

The presence of a weatherproof capability indicates that the fitting has been engineered with appropriate materials and seals to protect against ingress of water, dust, and other contaminants. Consequently, such fittings are critical in maintaining the integrity of electrical systems outdoors, where exposure to the elements is unavoidable.
