Industrial Sight Glasses

Large and durable
Canty Fuseview sight glasses feature the extra-large Fuseview window.
That means when you order a 4” sight glass, you actually get a true 4” view into the tank.
At the same time, this is the strongest sight glass available on the market.
The glass is capable of withstanding extreme mechanical stress such as impacts, vibration, high pressure, and high temperatures—without cracking or breaking.
This strength comes from the unique manufacturing method, where the glass and metal ring are fused together into a single unit—hence the name “Fuseview.”

A sustainable sight glass
These sight glasses are easy to remove for cleaning and inspection.
They can also be reused multiple times—for instance in other tanks or for future applications.
This makes Fuseview sight glasses a sustainable choice, supporting production practices where materials are reused rather than discarded.

Available in standard ANSI or DIN sizes
The sight glasses are available with standard ANSI or DIN connections and can be delivered with various certifications, including material compliance and testing documentation.
In many cases, specific ASME code requirements apply to tank installations.

Optional built-in light source
As a special option, Canty sight glasses can be supplied with integrated LED lighting.
This eliminates the need for an additional tank port for installing an external light source.
In these models, the light is built directly into the sight glass—making it a single, compact unit requiring just one tank connection.

Automatic cleaning of the viewing area
Canty sight glasses can also be supplied with a special cleaning ring equipped with small nozzles—a so-called “Jet Spray Ring.”
Through this ring, a cleaning solution or compressed air can be injected, which is forced through the nozzles in the metal ring to deliver high-pressure cleaning of the internal surface of the sight glass.
This practical option ensures a consistently clear view into the tank.

Versatile applications
These sight glasses are ideal for installation in all types of tanks, fermenters, reactors, and vessels where visual inspection of the internal process is needed.
