Enviroseal provides OEMs with numerous industry-wide applications. The automotive, marine, industrial, construction, technology and other applications are wide-ranging and very effective. Click here to visit our applications page and learn more.

Tiny voids, holes and micro leak paths are inherent in many molded electronic components and wires. These conditions can result in intrusion of foreign materials. The Enviroseal process eliminates these voids and leads to stronger performance.

Enviroseal is a highly advanced vacuum impregnation process that permanently seals parts with better quality control and higher production rates than other sealing methods.

Welcome to Enviroseal


Enviroseal is a sealing solution provided by Magna Tech Manufacturing. The Enviroseal process is highly effective for wires, wire harnesses, terminated connectors, thermistors, over-molded coil windings, and insert and injection mold components that are exposed to harsh environmental conditions.

The Enviroseal method of sealing can be performed cost-effectively and efficiently to provide you with a sealed wire or component that blocks out the imperceptible voids, holes and micro leak paths that are inherent in many molded electronic components and wires. Assuring your wire and component success and reliability with the Enviroseal process is our focus.

Our sealing process ensures part integrity. There is no change in the appearance or dimensional attributes of the components. Enviroseal sealing of these types of components can be performed more economically than applying epoxies and silicone blockers. Additionally, our Enviroseal process is a consistent batch process as compared to hand or spray-on applications.

We invite you to experience more about the Enviroseal advantage throughout this interactive website. To begin your engagement with us, please contact us.
