Uson Celebrates 60 Years of “Firsts” In Leak Testing Innovation.

Since 1963 Uson has set the bar for leak testing technology. Established in Houston, Texas by Rice University graduate William J. Raptson Jr., Uson is the world leader in the design and manufacture of leak test equipment and is regarded as the pioneer of modern leak testing. Uson’s first major business venture was marketing a gas sensing leak detector developed by U.S. Naval Research Laboratories. Little did Mr. Rapson know that this was the catalyst for Uson setting industry standards for the next 60 years.
