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. For all practical purposes E-I Compression Seals are indestructible. No special skill is required to apply, and assembly is rapid as all metal parts are tin dipped.
