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.

Combining the transparency of glass with the high heat resistance of ceramic, glass ceramic withstands temperatures up to 1255° F and resists rapid temperature changes.

Made of aluminosilicate that’s been chemically strengthened, this glass handles more wear and tear than other glass before scratching, cracking, or chipping. It’s often seen on mobile devices and enclosure display windows.

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.

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.

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.

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

At only half the weight of glass, polycarbonate maintains excellent impact resistance across a wide temperature range. It's comparable to Lexan, Hyzod, Tuffak, and Makrolon.

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

Because PVC resists acids and alkalies, it is often used in tanks and chemical-processing applications where visibility is essential.

Static cling allows this PVC film to stick without an adhesive.

Because PVC resists acids and alkalies, it is often used in tanks and chemical-processing applications where visibility is essential.

PETG can be formed into complex shapes without sacrificing durability.

Widely used as shipping tubes, this cellulose is also known as butyrate.

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.

Because PVC resists many acids and alkalies, it’s widely used for tanks and in chemical-processing applications. Also known as PVC Type 1.

Polycarbonate maintains good impact resistance across a wide temperature range. It's comparable to Lexan, Hyzod, Tuffak, and Makrolon.

The addition of glass fibers to this polycarbonate increases tensile strength for use in structural applications.

These selector packs come with one 2” square of acrylic, cast acrylic, cellulose, PETG, and polycarbonate.

Resistant to scratches and scuffs, mirrored acrylic is an economical alternative to mirrored polycarbonate.

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.

Mount these sights from the inside of your tank and secure with a lock nut.

Fasten the extended flange to tank walls.

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, such as hydraulic systems where overflow is a concern.

Monitor hydraulic fluid or oil level in gear boxes, crank cases, and other reservoirs.

Check the level of liquids containing chemicals such as alcohol-based solutions, boric acid, and sodium bicarbonate.

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

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

Simultaneously monitor the hydraulic fluid or oil level and temperature in gear boxes, crank cases, and other reservoirs.

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.

The indicator moves when flow is present, so it’s easy to visually confirm flow from a distance.

A large tubular window provides an unobstructed view of liquid color, clarity, and movement from multiple angles.

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.

Add these hollow microspheres to epoxy, urethane, or polyester resins to reduce weight and shrinkage.
