Explosion-Proof Wire Bushings

Seal tight connectors, also referred to as Sealtite connectors are electrical cable glands used in hazardous locations. Wire or cable passes through the center of the fitting with a locking nut that tightens to the outside diameter of the cable jacket. Various configurations are available, each with hazardous area ratings. Seal tight connectors offer a […]
