Q: Does the "M7" Hazardous Location Housing require sealing?

A: Yes! Conduit sealing serves two main purposes. Firstly, it prevents explosions and flames from spreading within the conduit and equipment, ensuring that they are contained within specific areas. Conduit seals are typically required near the entry point of explosion-proof enclosures to achieve this.
Secondly, conduit sealing helps to restrict the migration of gases or vapors from hazardous to nonhazardous locations. Properly installed sealing fittings effectively block the passage of these substances. It is important to ensure that the sealing process is carried out correctly to comply with codes and minimize the risk of property damage.
