MAXOS® Safety Sight Glass
MAXOS®—clear sight with definite safety
Whether in the chemical industry, the oil industry or the power supply sector, Maxos
safety sight glasses are proven and used all over the world whenever
visual inspections under extreme temperature or pressure conditions are
required in steam vessels, pressure tanks or pipeline systems.
The high safety level is secured by special borosilicate glass
of high chemical durability, exceptional purity and homogeneity. Along
with a low thermal expansion, which is typical for borosilicate glass,
thermal pre-stressing (tempering) creates a particularly high
resistance to sudden changes in temperature.
product line comprises a complete range of round and long sight glass
in varying dimensions to accommodate different pressure and temperature
