Bal Seal Engineering

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.
