2. Features
1. Heavy-duty multi-sealing structure with aging-resistant sealing rubber delivers superior explosion-proof, waterproof, and dustproof performance compared to standard glands; Ex db ⅡC Gb / Ex eb ⅡC Gb / Ex tb ⅢC Db certification ensures effective containment of internal ignition and prevention of flame propagation to the surrounding hazardous atmosphere.
2. High mechanical strength body materials (nickel-plated brass, SS304, SS316L) with PA6 anti-rotation washers provide excellent corrosion and salt-spray resistance, reliable cable retention, and vibration resistance in demanding industrial conditions; multiple thread options (M, NPT, G, PG) support flexible wiring configurations.
3. Fully compatible with LD Electric explosion-proof enclosures and cabinets for seamless integration; the threaded rear end design enables secure cable entry with built-in strain relief and anti-loosening functionality, offering customizable specifications and materials to meet specific project requirements across diverse on-site conditions.
