- Unsurpassed resistance to pressure, impact and temperature
- Simple, stress free installation ‑ resistant to bending, overtightening and impact

Applications
METAGLAS® can replace conventional glass in many applications including circular assemblies welded onto vessels, weld neck &
nozzle flanges and visual flow indicators. In addition, Metaglas® cover flanges can be mounted onto flat face base flanges, which are
available for all international flange connections including ANSI, BS & DIN. Existing installations can therefore be easily retrofitted to
improve safety and extend equipment life.
The unique properties of METAGLAS® also make it ideal for use with hygienic systems. MetaClamps® are available as sight glass caps
for sanitary clamp connections and In‑line systems. Sight glasses and Luminaire adaptors for sterile flush mount designs, such as the
NA‑Connect and TCI ClampConnect™ fittings are also available.
METAGLAS® has been subjected to the most rigorous tests by specific third party testing facilities in the chemical and pharmaceutical
industries and has subsequently been integrated into their standards.
