Bal Seal Engineering

Bal Seal Engineering We make seals, springs, and contacts that make your designs great. What does your company do? Passionate and Principled
On top of all that, there are the people.

Combining proven products with more than 65 years of engineering experience, we help improve the performance and reliability of equipment used everywhere - from deep sea to deep space. If you make pacemakers, airplanes, or wind turbines, that’s probably an easy question to answer. But when you’re in the business of engineering components that work inside these and other important machines, helping

people understand your company’s value can be a little more complicated. Small Parts, Big Advances
At Bal Seal Engineering, we make custom seals, springs, and electrical contacts that improve the performance and reliability of critical equipment used everywhere – from deep sea to deep space. Although they’re often measured in millimeters, our proven, precise products have a profound impact. They make active medical implantables smaller and more functional, simplify orthopedic implant and instrument design for reduced patient risk, improve the accuracy of diagnostic and analytical equipment used in disease testing and drug development, and even protect spacecraft – like NASA’s Curiosity Rover – in conditions that are literally out of this world. Not Just Products
But the components we make are only part of the story. There’s also our collaborative engineering process, which enables designers to advance their technology, achieve a competitive edge, and sometimes even shape industry standards along the way. And, there’s our application knowledge base, built on more than 60 years of successful engineering, testing, and development. As individuals and in teams, we are an engineering and manufacturing force to be reckoned with, driven to solve challenges and innovate like no other company can. Guided by the very same principles of honesty and integrity that led our company founder, Pete Balsells, to his early successes, we are promise-keepers and quality-seekers. We don’t take your trust, or the importance of your products, for granted. And we never will. Community and Culture
Surrounded by the natural beauty of California and Colorado, our ISO-certified manufacturing facilities symbolize the evolution of our company from a small mid-century startup to a modern, world-class design and manufacturing organization. We support the communities in which we’re rooted, we provide educational assistance for our associates, and we emphasize the importance of wellness and balance. Beyond geographic boundaries, we are active members of industry organizations – like the ISO Connector Task Force for IS-4 Standards, and the Charging Interface Initiative e. V. – that strive to improve quality of life and set new technology standards. The Right Relationship
Operating as an independent division of the Bloomfield, CT-based Kaman Corporation, we are “a Kaman company.” This structure allows us to remain agile and entrepreneurial as we leverage our parent company’s scale, resources, and complementary capabilities. We’re proud to be part of Kaman, a company with a past so similar to our own, and a commitment to positively shaping the future.

Three jobs. One spring.
When every component in your semiconductor equipment has to earn its place, multifunctionality matters. A Bal Spring® canted coil spring doesn't just shield against EMI/RFI, it also delivers reliable electrical grounding and mechanically connects with precise, controllable forces.

That means fewer parts, simpler assemblies, easier maintenance, and more reliable equipment. Check out the infographic to see how this 3-in-1 technology is helping fab and test equipment designers do more with less.

How can a simple spring take your semiconductor equipment designs to the next level? By delivering more than EMI/RFI shielding.

Our Bal Spring is a precision-engineered 3-in-1 solution that combines exceptional EMI/RFI shielding with electrical conductivity and mechanical retention in a single component. The result? Fewer parts, simpler assemblies, easier maintenance, improved reliability, and more equipment uptime.

If your current shielding tech can't do all that, it may be time to think about a spring. See ours in action: https://www.balseal.com/spring/shielding/

Longer maintenance intervals start with smarter sealing strategy.
This blog examines how the right seal geometry, materials, rinse systems, and hardware tolerances can help prevent premature pump failure, reduce leakage, and extend the life of critical IVD equipment. If you’re designing for accuracy, uptime, and reliability, it’s worth a look.

Long before the factory floor, the lab, or the launch pad, there's a first spark of interest in engineering. That’s why we’re proud to support Mater Dei High School’s Varsity Robotics Team during the 2025–26 FIRST Robotics Competition season. With the help of sponsors, mentors, and countless hours of hard work, they advanced to the playoffs in two competitions this year.
Congratulations to these talented young engineers and problem-solvers. We can’t wait to see what you build next.

Heat is the enemy. But bulk isn’t always the best defense.
The Bal Spring canted coil spring flips the script, moving heat away from critical interfaces without grease, ceramics, sinks, or oversized hardware. The same design that helps it keep its cool in electrical conducting applications is a built-in pathway that lets you do thermal management your way. Put a spring in your toolbox:

This wall in our Engineering area says it best: DRIVEN to solve, built to INNOVATE. And more often than not, we’re the team customers turn to when the “standard solution” isn’t cutting it.

Tight tolerances? Harsh environments? Conflicting requirements? That’s where things get interesting.

If you’ve got a challenge that’s bending the rules, we’re probably already leaning into it. Put us to work: https://www.balseal.com/design-request-form/
