Elesa+Ganter 111011-NP HCK.127-ZN-M12-NBR-PC-NP Oil Level Indicator

The Elesa+Ganter 111011-NP oil level indicator, identified as HCK.127-ZN-M12-NBR-PC-NP, is a column level indicator designed for visual oil monitoring in hydraulic tanks, machine reservoirs and lubrication systems. It shares the same 127 mm format as the protected version but is supplied without front protection, as indicated by the NP code.

Technical Configuration

This model includes zinc-plated steel fixing hardware, an M12 screw connection, an NBR O-ring and a transparent polycarbonate tube. The PC tube execution is designed for oil applications, while the NBR seal supports use in standard operating conditions up to the defined temperature limits of the series.

Elesa+Ganter 111011-NP Oil Level Indicator When to Use the NP Version

The NP version may be selected when the installation area is protected, when direct access to the tube is preferred, or when machine layout does not require an additional front guard. It is often suitable for enclosed machinery, protected hydraulic compartments or reservoir locations where mechanical impact risk is low.
