Hexagonal plug is an external threaded seal with a hexagonal head design, used to seal unused interfaces in pipelines, electrical equipment, or explosion-proof junction boxes. The core functions include:
Sealing protection: prevent foreign objects such as water, dust, and corrosive gases from entering the interior of the equipment.
Explosion proof safety: Block the entry of flammable gases or dust in explosive environments to reduce the risk of explosion (in compliance with Ex d II C explosion-proof standards).
Interface protection: Provide temporary/permanent sealing for backup cable holes or pipe openings to prevent mechanical damage or medium corrosion
