Specialty Seal Group (SSG) ceramic-to-metal and glass-to-metal seals give top performance in the harshest environments.

Whether you need industrial heaters, power cables, or other high heat or power sources to operate with maximum efficiency, SSG has a custom or standard solution that’s ideal.

All SSG seals are vacuum-tight and offer the necessary resistance to heat, abrasion, chemicals, oil, grease, moisture, toxic fumes and more.

We attach metals to seals through a variety of brazing and soldering techniques which we use based on your specific application.

Metalized Ceramics

Metalizing Protects & Bonds Ceramic Components

Metalizing is the moly-manganese coating applied to a seal’s ceramic component. It enables the seal to bond hermetically to the metal portion of the seal.

One of the keys to Specialty Seal Group’s success is the strength and permanence of our metalizing interface. More than 50 years of ongoing research & development have yielded formulations and processes that have given us the distinction of having the industry’s highest-quality metalizing.

Specialty Seal Group monitors metalizing strength every day through in-process control by Push-Test analysis (see Statistical Process Control graph at right). Quality control can provide lot integrity and statistical evidence to assure product reliability.
