Glass Lined METAGLAS® Sight Glass

Glass lined metal fused sight glasses combine the safety of a mechanical pre stressed sight glass and the exquisite properties of glass lined surfaces.

New products, new techniques in the chemical, pharmaceutical and food industry require material properties that only this long-time-known material can afford.

Enamel is highly resistant against corrosion, hard-wearing, not diffusing and inert (no catalytic effect).

For installation and operation the general conditions of glass lined vessels are valid.
