Monitor hydraulic fluid or oil level in pressurized applications, such as hydraulic systems where overflow is a concern.

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.

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

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

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

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.

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

For visual confirmation of flow from a distance, these sights have a ball indicator that moves when flow is present.

Withstand twice the temperature of standard sights. These are rated for temperatures up to 400° F.

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

Barbed fittings slide into soft plastic and rubber tubing.

Designed for more than 10 times the pressure of standard flowmeters for oil, these are rated for pressures up to 3,500 psi.

Measure the flow rate of hydraulic and motor oil.
