These E-I Glass Seals are super-rugged, feature extremely high strength and are difficult to put under stress. They are absolutely rigid, highly resistant to shock.

In this exclusive E-I compression construction, the glass remains under constant compression and is therefore extremely strong. These compression-type seals possess extraordinary immunity to shock, vibration and pressure changes-are practically indestructible.
