THE METHOD OF MAKING A THERMOSTAT ELEMENT HAVING A REMOTE BULB CONNECTED BY A FLUID-FILLED TUBE TO A PRESSURE RESPONSIVE ACTUATOR TO FORM A FLUID-FILLED SYSTEM, WHICH CONSISTS OF ATTACHING A BULB AND AN ACTUATOR TO OPPOSITE ENDS OF A LENGTH OF ROUND TUBE, FILLING THE BULB, THE TUBE AND THE ACTUATOR WITH A RELATIVELY NONCOMPRESSIBLE FLUID AT AN OPENING, ROLLING THE TUBE TO REDUCE THE CROSS SECTIONAL AREA TO A TRIANGULAR SHAPE SO THE CENTER BORE HAS A SUBSTANTIALLY TRIANGULAR CROSS SECTIONAL AREA, AND SEALING SAID OPENING TO PREVENT THE LOSS OF FLUID WHEN THE FLUID IN THE BULB EXPANDS.
