Abstract
One or more techniques and/or systems are disclosed for interrupting fluid flow when experiencing fuel leaking conditions, such as an out of specification connection between the fuel source and a device utilizing the fluid. A distal end of a valve body has interfaces with at least a portion of a connection to a fluid supply; and a proximal end interfaces with at least a portion of a fuel intake. An internal passage runs between the proximal end and distal ends of. A displacement member in the internal passage comprises a distal portion that extends out of the valve to engage a valve to the fuel supply. A retention cap selectably engaged with the valve body can comprise a material that deforms under force at a predetermined temperature, resulting in a release of the displacement member under a biasing force form a biasing component between the cap and displacement member.
