With expertise in the design and manufacture of various hermetic seals, we offer customized hermetic seals suited for all your leak-tight power feed thru requirements. Our capabilities cover every facet of manufacturing custom seals – from initial design plus prototype production to high volume manufacturing. In addition, we have the ability to work with different materials for the body, insulation, and conductor parts of your hermetic seals. Seals can be designed to withstand very high temperatures, pressures, or other extreme environmental condition. We manufacture custom hermetic seals from stainless steel, Inconel, mild steel, titanium molybdenum, titanium, as well as other exotic alloys.

We also offer plating options such as gold plating, silver plating, and electrolytic nickel plating. A number of industries, including defense, telecommunications, aerospace, and automotive electronics use our custom hermetic seals.
