High-Pressure Oil-Level and Temperature Indicators
Screw-In Mount
Through-Wall Mount
Screw-In/Through-Wall Mount
Check both the temperature and the hydraulic fluid or oil level in a pressurized system. These indicators are often used in hydraulic systems where overflow is a concern. The aluminum gauge shield protects the glass window from impact.
Screw-in indicators mount from the outside of your tank into threaded pipe or threaded holes.
Through-wall indicators mount from the inside of your tank through unthreaded holes. Secure with nuts on the inside of your tank.
Screw-in/through-wall indicators give you the option to mount from the inside or outside of your tank. Use the mounting nuts on the inside of your tank to attach them through unthreaded holes or thread them into pipe or threaded holes on the tank’s outside.
Indicators with a red line emphasize the level of clear liquids, so they’re easier to read.
