Ideas. Solutions. Success.
A Conax tradition since day one.
In 1948, Cornell University graduate and Buffalo Electro-Chemical engineer Maurice W. Connell was approached by friends who were unable to come up with the means to measure temperature in a high-temperature, high-pressure reactor of a very small size.
In the basement of his home in suburban Buffalo, New York, Connell developed an idea for a device that, for the first time, could measure temperature very rapidly in high-temperature, high-pressure environments. His solution—the high-speed thermocouple—was the catalyst for developing a highly-successful, worldwide company that began with a $450 investment and has grown to a multi-million dollar enterprise.
Along with adaptations of basic thermocouple technology, Connell designed and marketed a specialty pressure vacuum seal that could be used across many applications. Designed for conductors and probes that enter chamber housings in harsh environments, this sealing technology was a forerunner of the electrical penetration technology and many other seals for high pressure and extreme temperature environments that remain staples of industry today.
Maurice W. Connell forms Conax Corporation, and first-year sales of his newly-patented high-speed thermocouple reach $9,000. Shown above is Joe Gennocro with the first Conax van.
Conax Corp. begins construction of a new $200,000 plant at its current location on Walden Avenue in Buffalo, New York. The company’s existing workforce of 25 is projected to increase to 40 the following year. The primary products remain thermocouples used in jet engines and atomic submarines. However, Conax has already expanded its offerings to include pressure seals used by the military and in deep-sea exploration, as well as explosive-actuated valves for guided missiles.
Conax begins work on a $100,000 addition to its new plant, adding 6,000 square feet to expand its manufacturing capabilities and provide office and engineering space for the company’s more than 70 employees.
After 10 years, Conax Corporation’s annual sales volume reaches $2 million, with 120 employees serving 4,000 industrial customers worldwide.

Conax employees watch John Glenn orbit the Earth as part of NASA’s Project Mercury, knowing that explosive-actuated valves manufactured by Conax have played a role in the mission’s success. The company’s contribution to the mission is just the beginning of what will become a proud heritage in the aerospace industry for Conax.
Conax designs and manufactures three small valves that play a major role in mid-course correction in the Mariner II spacecraft, whose mission was to fly within a distance of 10,000 miles of the planet Venus for various experiments—closer than any other device sent into space at that time.
Based on the strength of Conax’s thermocouples for the atomic energy industry, foreign sales increase by 400 percent. With representatives/ distributors in Italy, France, Belgium and Spain, an expansion of the company’s European footprint is planned to include new offices in England, West Germany and the Netherlands.
Conax breaks ground for a 10,000-square-foot expansion of its Walden Avenue plant.
Conax buys the Morrison-International Equipment Division of Ryder System Inc., increasing the company’s non-military and non-industrial product offerings to include display cabinets, tire racks and portable refreshment stands.
Conax acquires Beacon Devices Inc., a manufacturer of pressure cylinders and regulators, tire inflators and rescue torches. The company’s second acquisition of 1964 increases the number of employees to nearly 300 and puts Conax Corporation on pace for sales nearing $6 million in the 1964-65 fiscal year.
Conax develops a CO2 beer tap for use in home refrigerators. Orders from breweries for more than 250,000 units are taken even before the product is on the market.
Conax receives a patent for electrical penetration for nuclear applications. This patented electrical penetration became the standard bearer of the industry and remains so today, produced by Mirion Technologies.
