Abstract:
A drive nut for a fitting includes an interior socket centered on a central axis and configured to receive at least a rearward portion of a conduit gripping member. The socket is defined by a radial drive surface positioned to engage the conduit gripping member during pull-up, a first longitudinal surface radially outward of said drive surface and a tapered second longitudinal surface between the drive surface and the first longitudinal surface, wherein a conduit gripping device contacts the second longitudinal surface upon an initial pull-up and each remake. This geometry facilitates a greater number of available remakes by reducing lost stroke, and can provide less stroke loss for fittings pulled up by torque.
