About Hermetic Seal Technology, Inc.

Hermetic Seal Technology (HST) produces custom hermetic glass-to-metal seals for lithium batteries used in oil exploration (down-hole) and military applications. HST provides the best overall value and highest reliability whether the requirement is for a small quantity of prototypes or hundreds of thousands of seals.

For the healthcare industry, we custom design and manufacture a unique line of medical implantable titanium seals. HST specializes in manufacturing titanium glass-to-metal seals for lithium batteries used in medical implantable devices such as pacemakers, heart defibrillators, and neuro-stimulators. Each and every medical seal is not only 100% leak checked but is also 100% visually inspected under high magnification by an HST engineer.

We also offer customized hermetic seals suited for all your leak-tight power feedthrough requirements including industrial, sensor, and aerospace applications.

For over 25 years, Hermetic Seal Technology has provided precision glass-to-metal hermetic seals and connectors to customers worldwide. With 100% leak checking on all seals and with Clean-Seal technology, HST is a true leader in glass-to-metal sealing technology. Let our engineers help design and build your hermetic application.
