A fluid control assembly includes a body having a female threaded end port, and an end adapter including a male threaded end screw threadably assembled with the female threaded end port, an end connector, and an internal passage extending from the end connector to the end screw. One of the body and the end adapter includes at least one outer peripheral recess, and the other of the body and the end adapter includes a peripheral flange. A portion of the peripheral flange in circumferential alignment with the at least one recess is deformed into interlocking engagement with the at least one recess to rotationally secure the end adapter with respect to the body.

The invention relates to a fitting provided on the end of a pressurized hose or pipe. The invention provides a fitting having a spigot and a ferrule part in which opposing recess and projecting parts are provided to engage each other and prevent the two parts unwinding from each other.

A connection socket for a tubular connection that includes: a socket cup having a metal alloy composition and a sealing portion, the sealing portion comprises a primary and a secondary sealing recess; a primary seal positioned within the primary sealing recess, the primary seal comprising an elastomeric material having a service temperature, and a secondary seal positioned within the secondary sealing recess, the secondary seal comprising a metal composition. Further, the secondary seal has a melting temperature at or above the service temperature of the primary seal.
