Abstract: A fitting assembly includes a first component having a metal male threaded port including a male tapered threaded portion and an end face and a second component having a metal female threaded port including a female tapered threaded portion and a counterbore, the female threaded port threadably receiving the male threaded port. An apertured metal insert is disposed between the end face and the counterbore and includes first and second seal surfaces. When the first component is tightened with the second component, the metal insert is engaged between the end face and the counterbore, such that the first seal surface seals against the end face and the second seal surface seals against the counterbore, to provide a metal-to-metal seal between the male threaded port and the female threaded port.

Abstract: A method and apparatus for setting a desired load applied to a device such as a valve. A tool is applied to the valve. Force applied to the tool is transmitted to the valve packing. A selected load force is applied to the tool. The packing is secured to set the selected load force applied to the packing. The tool may be removed from the valve.

Abstract: A ball valve includes a valve element and a single piece packing that seals the valve element within a valve cavity. The single piece packing is installed over the valve element at room temperature or may be molded thereon. The valve element may include a flow control element such as a ball and upper and lower trunnions. The various dimensions of the valve element and packing are selected to facilitate room temperature assembly and to substantially reduce the volume of packing material, thereby improving the performance of the valve over wider temperature ranges and pressure ratings.

Abstract: A ball valve includes a valve element (22) and a single piece packing (32) that seals the valve element within a valve cavity (20). The single piece packing is called over the valve element at room temperature or may be molded n. The valve element may include a flow control element such as a ball (24) and upper (28) and lower (30) trunnions. The various dimensions of the valve element and packing are selected to facilitate room temperature assembly and to substantially reduce the volume of packing material, thereby improving the performance of the valve over wider temperature ranges and pressure ratings.
