An insulating gas unit, and a method and apparatus for filling and sealing the insulating gas unit with an insulating gas, such as argon or krypton. The insulating glass unit includes a spacer frame having at least one elongated or oblong opening dimensioned to receive a gas filling nozzle. A mating elongated or oblong plug is dimensioned to be received within the opening in order to seal the insulating space of the insulating gas unit. A dimpling tool engages with the plug to form dimples that secure the plug in the opening.
