Explosion proof fittings, other names explosion proof electrical fittings, explosion proof cable gland, explosion proof connector, 3 4 to 1 2 reducer bushing, 1 to 3 4 reducing bushing, explosion proof conduit fittings, explosion proof flexible conduit, hazardous location fittings, explosion proof cable, flameproof cable gland, waterproof cable gland, explosion proof conduit, explosion proof conduit seal off, explosion proof conduit sealing compound, sealing fitting, conduit seal, condulet. Explosion proof fittings is structured with flame proof body, connector and thread to connect cable and conduit, increased safety cable gland to fix the cable to protect the electrical cable conductors. On the basis of different functions, explosion proof fittings are classified to three kinds, explosion proof cable gland to connect cable directly, explosion proof connector to connect the conduit directly and compactly where cable passed through, explosion proof conduit fittings to connect conduit directly with quick programming changes, sealing compound and flexible length extending. Material ranges from anti-corrosive polyamide to high strength metal, explosion proof fittings can be installed together with explosion proof lighting, explosion proof junction box, explosion proof panel, explosion proof enclosure to meet class 1 division 1 conduit requirements, class 1 division 2 conduit requirements, class 2 division 1 and class 2 division 2 conduit requirements.
