Abstract: A fluid fitting for use with a hydrocarbon production device includes an annular fitting assembly inserted into a port formed in the hydrocarbon production device. A first outer diameter seal is located between the fitting assembly and the port. A packing assembly is located in an annulus between the fitting assembly and an inner surface of the port, defining a second outer diameter seal between the fitting assembly and the port.

Abstract: Apparatus and methods for connecting a linear actuating mechanism of an actuator to a valve stem of a linearly actuated valve, are provided. An example of an apparatus can include an elongate valve stem member of a valve, an extension member of a linear actuating mechanism, a locking cap member, and a locking member insertable into the locking cap member for locking the valve stem member with the extension member through employment of the locking cap member.

Abstract: A seal assembly for use in a valve that maintains a seal during operational excursions of high temperature, such as during a fire. The seal assembly includes a eutectic material that retains an energizing element in place during normal conditions, which in turn keeps a secondary seal spaced axially away from a sealing position. During high temperature excursions, the eutectic material degrades and releases the energizing element. When released, the energizing element energizes a secondary seal that is in an annular space between a valve stem and valve housing.
