The present invention relates to a ferrule-type fitting for forming a fluid-tight seal between an insulated electrical conductor extending from outside a well to a wellhead barrier and a rigid tube that projects outside the wellhead barrier. The rigid tube surrounds the electrical conductor and extends through the wellhead barrier for routing the electrical conductor. The ferrule-type fitting is comprised of a tubular body fitting with an elongated opening sized and shaped to fit around the rigid tube. The opening includes a conical counter bored section adjacent to one end for forming a gap between the body fitting and the rigid tube. The body fitting includes an outer threaded surface on the one end. A ring shaped ferrule bushing is formed of a material softer than the material of the rigid tube, which has the tendency of returning to its original shape after being deformed. The ferrule bushing is sized and shaped to fit around and directly contact the rigid tube and interface the conical counter bore section with the gap. A nut fitting is provided which includes a threaded inner surface for engagement with the outer threaded surface of the body fitting. The nut has a shoulder for engaging the ferrule bushing. The shoulder engages the ferrule bushing so that the ferrule bushing is deformed to engage and crimp the rigid tube. This provides a fluid-tight seal between the inner surface of the rigid tube and the insulated electrical conductor after the nut fitting is tightened onto the body fitting. The ferrule bushing is not hard enough to permanently engage the rigid tube, but returns to its original shape so that it can be removed from the crimped rigid tube when the nut fitting is loosened and removed from the body fitting.
