A coupling for a vacuum system includes a socket member and a plug member. The socket member has a body defining a through bore opening at a front face. A cover supporting a gasket is pivotally carried on the socket member and adapted to cover and seal the through bore opening. The plug member includes a body defining a tubular nipple dimensioned to be received within the socket member through bore. A seal is carried by the plug member and positioned to engage the front face of the socket member when the nipple is inserted into the socket member. A lock pin is carried by the cover and dimensioned to fit within a recess defined by the plug member body.
