2. Features
1. Reinforced heavy-duty multi-sealing structure with optional silicone seal material delivers IP66–IP68-rated waterproof and dustproof performance; while the inner cable sheath is not explosion-proof sealed, the gland body carries Ex db ⅡC Gb / Ex eb ⅡC Gb / Ex tb ⅢC Db certification, providing robust mechanical and environmental protection for cable entry in hazardous locations.
2. Corrosion and salt-spray resistant body materials (nickel-plated brass, SS304, SS316L) with PA6 anti-rotation washers deliver high mechanical strength, reliable cable retention, and vibration resistance in demanding industrial conditions; multiple thread options (M, NPT, G, PG) support flexible wiring configurations across diverse installations.
3. Fully compatible with LD Electric explosion-proof enclosures and equipment for seamless integration; offers customizable specifications and materials to meet specific project requirements, with the reinforced design particularly suited for offshore, chemical, and heavy-duty industrial environments where long-term reliability under harsh conditions is essential.
