Abstract
A V-band coupling for use on an explosion-proof enclosure. The V-band coupling includes a V-band having a toughened layer along its interior surfaces for gripping the flanges on the enclosure which the V-band engages when it is installed on the enclosure. The roughened layer results in an increased coefficient of friction between the V-band and flanges which is effective for reducing the load experienced by the trunnion joints of the coupling during explosion events thereby allowing the explosion-proof enclosure to withstand high internal pressures without system failure.
