Abstract: Thread joints in explosion-proof electrical fixtures for hazardous areas must relieve the momentary pressure from an internal explosion without flame propagation to the exterior. Ordinary paint on the threads cannot be used due to variations in thickness which alter the flow characteristics and the cooling effects.
