The TGSA thermal fuse is a safety device in gas installations against the propagation of fires, since it consists of a thermal fuse that shuts off the gas supply at a temperature above +95ºC. The thermal fuse is perfect against accidental breakage of the pipe downstream of the appliance tap as it has an integrated safety shutter that automatically stops the gas flow in case of breakage, tearing, cutting of the pipe after the tap and exceeding the flow rate of 1.6 m3, preventing dangerous gas leaks. For kitchen connection applications using multilayer piping.
