PROBLEM TO BE SOLVED: To provide an improved sealing gland used for preventing fluid flow, pressure transmission and flame propagation, and suitable for use in a hazardous environment. SOLUTION: This sealing gland 20 suitable for use in a hazardous environment is adapted to prevent fluid flow, pressure transmission and flame propagation between the gland and the penetrant portions of insulated electrical wires passing therethrough, and within and along such penetrant portions. The improved sealing gland includes a tubular body 21, a first insulator 22, a sealant 23, a second insulator 24, a follower 25, and a cap 26. The sealing gland is so dimensioned and proportioned that, when the cap is tightened on the body, the sealant is deformed into fluid-tight pressure-sealed engagement with the body and wire to prevent fluid flow, pressure transmission and flame propagation between the gland and wires, and within and along the penetrant portions of the wires.
