During a conduit installation, what is needed to prevent moisture ingress?

To prevent moisture ingress during a conduit installation, the use of airtight fittings is essential. Airtight fittings are specifically designed to create a secure seal that keeps moisture and other external elements from entering the conduit system. This is crucial as moisture can lead to corrosion, deterioration of materials, and ultimately affect the performance and safety of the electrical system housed within the conduit.

Airtight fittings ensure that joints and connections in the conduit are tightly sealed, which is vital in maintaining the integrity of the electrical installation, especially in environments that may be prone to humidity or water exposure. By using these fittings, you are effectively mitigating the risk of moisture-related issues that could compromise the system over time. In contrast, while sealants and adhesives may assist in creating barriers against moisture, they may not be as reliable as specialized airtight fittings that are engineered for this specific purpose.
