These sights have a glass window.

View tank contents from multiple angles through the plastic domed window.

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

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.

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.

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.

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

The nylon body and window make these indicators shatter resistant.

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