METAGLAS® Sight Glass Solutions for Vacuum & Special Applications
METAGLAS® sight glasses deliver world-leading safety, clarity, and reliability across the most demanding
operating environments. Whether installed on ultra-high vacuum systems or specialised hygienic and
chemical-processing equipment, METAGLAS® sets the benchmark for performance through its mechanically prestressed,
fused-metal construction.
METAGLAS® Sight Glass – Vacuum Applications
Designed for high vacuum and ultra-high vacuum (UHV) environments, METAGLAS® vacuum-rated assemblies
offer exceptional sealing integrity, minimal outgassing, and superior mechanical strength.
The fused-metal construction eliminates the risk of catastrophic fracture, making them ideal for critical
scientific and industrial vacuum systems.
