Flexible Easy-View Liquid-Level Indicators
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. Use them in pressurized applications, such as hydraulic systems where overflow is a concern. They mount from the outside of your tank.
