Sealing, Connecting, Conducting, EMI Shielding, and Consultative Engineering

Our seals, springs, and electrical contacts improve the performance and reliability of critical equipment used everywhere – from deep sea to deep space. But our precision components are only part of the story. There’s also our consultative engineering process, which helps designers 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 over 60 years of successful engineering, testing, and development.


Our engineers gain a deep understanding of your application.


Together, we engineer a solution that elevates your design.


In as quickly as two weeks, you get a prototype.


You’re ready to scale up, from 10s to 1,000,000s of pieces.
