Housings for Sightglasses

Product Description

Certain applications in the industrial sector rely on sightglasses (otherwise known as gauge glasses) to monitor different fluid levels (oil, coolant in air conditioning systems). These sightglasses enable fluid levels to be read quickly and efficiently.

We offer specially produced, hermetically sealed sightglasses with robust metal frames.


Due to our extensive experience with optical glases, we are able to offer particularly long-lived types of glass that are capable of withstanding aggressive substances as well as high temperature fluctuations, while simultaneously providing a clear view into the inside of the housing. The housing components can be adapted to accommodate the customer requirements.


For monitoring fluid levels in industrial areas.

Technical Details


These gauge glasses are manufactured using particularly robust and transparent types of glass with excellent optical properties, mounted in steel and stainless steel frames.

In addition, to ensure the reliable hermeticity of the sightglasses, glass-to-metal sealing technology is used. Please click on this page for more information.
