fred lennonA Fitting Legacy

Swagelok Company is proud to celebrate over 75 years in business! We continue 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.

With a $500 loan from his wife’s uncle, Fred A. Lennon founded our company in July of 1947. Reaching this remarkable milestone is a testament to his vision: a values-based culture; ongoing investments in our workforce and infrastructure; an evolving and innovative sales and service model that sets us apart in the industry; and a commitment to customers who count on us for high-quality products, services, and solutions.
