In environments where refrigerants or other compressed materials are contained in a sealed system, our GTM hermetic feedthroughs allow a secure and reliable means to pass electrical power from an outside source to the motor inside. Highly compressed seals for hermetic sight glasses are used as windows for visual level and flow indicators in high‑pressure or vacuum applications.
