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.

These sheets won't deform when exposed to temperatures up to 2100° F or from drastic temperature changes.

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.

This extruded acrylic offers similar performance as cast acrylic at a lower cost.

With a clear coating that provides protection from abrasion, UV light, and harsh cleaners, this polycarbonate is often used to create transit shelters and equipment shields.

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.

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

The nylon body and window make these indicators shatter resistant.

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

Seal the glass on your level indicator.

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

Monitor liquid level in applications that have vibration, high pressures, and high temperatures. These indicators are also known as armored level gauges.

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.

Compact in size, these guards can be mounted directly to a machine or workbench. Panels are framed in aluminum T-slotted extrusions to provide multiple points of attachment for other components.

Combine posts, panels, and doors to create a barrier around equipment.
