Housings for Sightglasses

Product Description

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

We offer specially produced, hermetically sealed sight glass assemblies with robust metal frames.


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


Sight glass assemblies are used for monitoring fluid levels in industrial areas.

Technical Details


We manufacture sight glass assemblies 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.
