Abstract
Perforating gun connectors are provided with a small diameter inner tube to house the detonating cord and an outer load-bearing tube that is ported to be in pressure balance. The inner tube controls the volume in the gun for the well fluids to enter after the guns are fired and the initial pressure surge dissipates. The smaller diameter also increases pressure rating and diminishes the chance of plastic deformation. Since the inner tube is inset even some deformation is tolerated without distorting the outer tube due to the space between the tubes. A bored rod is used as a housing member or a layered single outer wall.
