2. Features
1. Ex db ⅡC Gb / Ex eb ⅡC Gb / Ex tb ⅢC Db explosion-proof certification ensures the gland effectively contains any internal ignition and prevents flame propagation; IP66/IP68-rated sealing with high-performance rubber gaskets provides excellent waterproof and dustproof performance.
2. Corrosion-resistant body materials (nickel-plated brass, SS304, SS316L) combined with Nylon 6 anti-rotation washers deliver strong mechanical structure, reliable cable fixing, and long service life in harsh 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; supports both armored and unarmored cables with proper sealing compound filling and armor compression ring clamping, offering easy installation, stable sealing performance, and customizable specifications to meet specific project requirements.
