Unibloc Sight Glasses
Unibloc’s sight glasses are designed for use in the pharmaceutical, biotech, food and beverage, chemical and personal care industries, helping professionals meet their manufacturing needs for a wide variety of liquid types and processing requirements. Each of Unibloc’s sight glasses offers a stainless-steel construction, electropolished components and fine surface finishes as standard features that provide for enhanced durability and expert craftsmanship.
Unibloc offers two types of sight glasses: the Bulls-Eye and the In-Line, both of which offer superior performance for high and low pressure applications.
Our Bulls-Eye sight glass is fitted with two rigid glass view-ports on opposite sides for versatility in positioning the equipment as needed. Inside the retainers are gaskets, as well as a fine threaded ring that keeps the glass disks in place. The Bulls-Eye sight glass is ideal for extra protection during monitoring and observing your active process.

What is a Sight Glass?
A sight glass is simply a transparent window or tube installed within a tank or boiler system that allows an observer to study the contents inside, ensuring optimal quality and safety. For monitoring liquids and ensuring optimal safety in processes that involve pressurized systems or vaporization, sight glass windows are used to some extent. Industries such as utilities and power, pharmaceuticals, food and beverage, biofuels, wastewater treatment and management, and chemical/petrochemical all use sight glasses to monitor the status of their fluidic systems.
