Standard-Thomson Corporation began in 1926 as Clifford Manufacturing, a manufacturer of hydro-formed bellows. Since that time Standard-Thomson Corporation has become an industry leader in designing and manufacturing some of today’s highest performing automotive and heavy duty thermostats. STC’s product line covers all domestic and import thermostat designs. By employing a combination of a patented No or Low Leak Weir and Superstat Technology, Standard-Thomson delivers a robust product that improves performance while extending engine life.
In 1997, Tomkins PLC, a European conglomerate acquired Standard-Thomson and integrated with Gates Rubber Company/Stant/Plews/Edelman/Schrader Bridgeport/Schrader Electronics family, providing an instrumental combination of manufacturing talent and facilities to lead the world in the automotive and industrial fluid sealing and fluid conducting solutions industry. Today, we are part of Tomkins PLC.
