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.

Bend these flexible indicators around the contours of your hydraulic fluid, oil, or water tank. Because their plastic resists shattering, they don’t need a protective shield like other liquid-level indicators, so you can check your tank’s level from any angle.

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.

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

Often used in cooling, lubrication, and process systems.

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

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

A ball indicator increases the visibility of flow for checking at a distance.

The included mounting ring lets you install these sights in instrument panels.
