Introduction to Key High Vacuum Products

Key High Vacuum Products, Inc. offers the finest high-vacuum and ultra-high-vacuum products. Our distinction comes from our pursuit of perfection, trustworthiness, and close collaboration with our customers. Since opening our doors in October 1976, the company has been built on one principle: making the customer happy. This approach remains unchanged today. While our equipment and components have evolved, Key High’s dedication to customer satisfaction endures.

Key High was founded in October 1976 by Anthony and Elizabeth Kozyrski, known as "Betty & Tony." They had a clear vision from the start: to create a company that cares about its customers and takes pride in its work.

Tony was a machinist who made, welded, and leak-tested parts, among other tasks. Betty adapted to whatever Key High needed; they did everything together. Key High Vacuum Products, Inc. continues to be a family-run business, with the second generation now at the helm.

At Key High, we pride ourselves on our old-school values. We have never had a layoff, regardless of economic downturns or the COVID-19 pandemic. We care about our employees and prioritize our customers' needs, adhering to the golden rule of treating people as you wish to be treated. Key High is now approaching its golden anniversary, and we are grateful for the opportunities to work with incredible people, companies, and organizations worldwide.

Key High's website is user-friendly, making it easy to find and order the necessary parts. If you can't find what you need at keyhigh.com, please call us. We will answer the phone and may have the part in stock.
