Also known as Pyrex and Schott glass, borosilicate sheets are heat resistant, clear, and have a super-smooth surface. They're used in a range of applications, from high-temperature viewports to 3D printing.

Commonly used as sight glass.

Also called Pyrex and Schott glass, these glass tubes resist clouding and pitting and are highly chemical and heat resistant.

Able to withstand temperatures up to 2100° F, this quartz glass is useful in high-temperature applications that also require optical clarity, such as high-intensity lighting, fiber-optic production, and optical lens systems.

Blistering temperatures won’t melt these quartz tubes, and rapid temperature shifts won’t cause them to crack.

Very thin yet extremely durable, this glass has been chemically strengthened to maximize toughness and scratch resistance. It's often used for mobile device screens.

Also known as Macor, these glass-mica ceramic sheets and bars withstand temperatures up to 1470° F.

Machine complicated shapes and precision parts from these glass-mica ceramic sheets in a fraction of the time it would take using other types of fired ceramic.

Cast acrylic is easier to machine than extruded acrylic. It's comparable to Lucite and Plexiglas® Acrylic.

Cast acrylic is easier to machine than extruded acrylic. It's comparable to Lucite and Plexiglas® Acrylic.

A static-dissipative coating on this cast acrylic prevents electrostatic discharge from damaging sensitive electronic equipment.

Laminate or mold this plastic film onto credit card signing screens, signs, and other surfaces for a see-through protective layer that won’t scratch.

Enhanced UV resistance makes this polycarbonate better than standard polycarbonate for outdoor use.

Often used in security doors and windows to protect against forced entry, this laminated polycarbonate is nearly impenetrable.

The combination of high strength and water resistance, along with a variety of color choices, makes this opaque cast acrylic useful for outdoor signs and containers. It's also known as Lucite and Plexiglas® Acrylic.

These sights have a glass window.

View tank contents from multiple angles through the plastic domed window.

Easily view liquid movement and level changes from a distance—these sights have an indicator ball inside the glass window.

With a thick glass window fused to a metal body, these sights resist cracking at high pressures.

Fasten the extended flange to tank walls.

Press these sights into a hole in your tank wall; no additional mounting nuts are needed. They mount from the outside.

Monitor food, brewery, chemical, pharmaceutical, and biotech processing lines with these sights that attach to quick-clamp fittings for fast installation and easy removal for cleaning.

Replace existing gauge glass or combine with valves and guard rods to build your own level indicator.

Monitor hydraulic fluid or oil level in pressurized applications.

These flexible indicators bend to follow the contours of a tank.

Shut-off valves stop flow so you can clean and replace gauge glass without removing these indicators from your equipment.

Use these gaskets with heavy duty level indicators to seal the glass.

Mount these indicators from the inside of your tank through unthreaded holes.

For use with water, hydraulic fluid, and diesel, install these gauges through the top of your tank.

The low-profile body fits in areas with limited clearance.

To maintain a clear view of your process media without disrupting flow, twist the tubular window to clear debris and buildup with the internal wipers.

Protect personnel and equipment from debris with these portable panels.

Framed in aluminum T-slotted extrusions, these customizable machine guards provide multiple points of attachment for other components and structures.
