Swagelok's Legacy

Our Founding and Our Evolution

Founder Fred Lennon demonstrating Swagelok tube fittings

Fred A. Lennon founded Swagelok in July of 1947 with a $500 loan from his wife’s uncle. We have continued to grow and thrive by matching the speed of our customers and the pace of change in the world—without losing sight of our legacy of success.

Swagelok Company in the 1940s 



Fred A. Lennon meets Cullen B. Crawford. The revolutionary Swagelok® tube fitting, a two-ferrule compression type fitting, is developed.


Crawford and Lennon form Crawford Fitting Company. The following year, Lennon purchases the entire business and the patent for the Swagelok tube fitting from Crawford.


Lennon establishes a network of independent sales and service centers (SSCs), exclusive distributors of Swagelok products. The first SSC is R.S. Crum, established to serve the northeastern United States.

Swagelok Company in the 1950s



The first Crawford Fitting plant in Cleveland is the company’s home from 1950 to 1965.


The Swagelok product line expands with the creation of small, strategically focused companies that produced pipe fittings and needle valves, among others.
