1932 a new business was established in London to manufacture Sarco steam traps but under a different brand name: Spirax (derived from the helical spiral tubing which formed an integral part of the steam traps).
1935 Sarco set up its own factory in Pennsylvania, and the company became known as the Sarco Manufacturing Corporation. Sarco-branded steam traps and apparatus were exported to Europe; Sanders, Rehders & Co. had become a selling agent for Sarco products and changed its name to Sarco Thermostats
1937 Spirax Manufacturing Co acquired Sarco Thermostats, and moved to Cheltenham.
1940s Spirax was granted rights to trade Sarco products in the United Kingdom (excepting Canada), Ireland, Denmark, Holland, Portugal, Sweden, and Norway, while the U.S.-based Sarco retained the rest of the world's markets.
Early 1950s: Sarco International Corporation of New York, or Sinco, was formed, which retained the rights to produce Sarco products within North America and also acquired the Sarco steam trap rights outside North America, France, Belgium and the countries in which Spirax traded.
1952 Spirax purchased sole rights to Sarco products in the U.K.
1953 renamed as Spirax-Sarco Ltd.
1957 Spirax-Sarco Ltd. took over Sinco, gaining worldwide rights to the Sarco steam trap brand, other than in the United States and Canada. These remaining rights were subsequently purchased in 1983.
