Metal fused sight glasses are made by melting glass inside a metal ring.
The glass can be borosilicate glass or sodalime glass.
Borosilicate glass features a very high resistance against chemical influences and thermal shocks.
With Sodalime glasses, it is possible to manufacture metal-fused sight glasses with greater transparency.
The metallic materials we use are carbon steel, stainless steel, nickel-base alloys and monel.
