Safely and clearly view electronics inside enclosures in areas with explosive gases and dust. Made of glass, these windows protect your electronics from dust, weather, and washdowns.

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

The window and body are made from a single piece of plastic, making these sights more shatter resistant than sights with a glass window.

Machined from one piece of stain- and impact-resistant plastic.

Continuously monitor oil quality through the clear plastic reservoir and use the attached drain valve to remove water accumulation.

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

An extended flange makes these sights easy to bolt onto tank walls.

Add a window to your high-vacuum system. With a pane of glass sealed inside a high-vacuum CF flange, these sights bolt onto vacuum chambers, tee fittings, and manifolds.

Designed with quick-clamp (KF) connections, these sights connect to a port on a high-vacuum chamber, so you can monitor what's happening inside.

Use this gauge glass with heavy duty level indicators.

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

Check both the temperature and the hydraulic fluid or oil level in a pressurized system.

The nylon body and window make these indicators shatter resistant.

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

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.

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

Made with clear, shatter-resistant plastic, these indicators don't require a shield to protect them like other oil-level indicators, so you can check your hydraulic fluid or oil level from any angle.

Often used in cooling, lubrication, and process systems.

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

Rated for more than double the pressure of standard flow sights, these can withstand pressures up to 400 psi.

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

Barbed fittings slide into soft plastic and rubber tubing.

Made of FDA-listed materials, these sights can be used with food and beverage. They have sanitary quick-clamp connections for easy disassembly and cleaning.

About half the height of other flow sights for chemicals, these fit in areas with limited clearance.
