Elesa+Ganter 111021-NP HCK.176-ZN-M12-NBR-PC-NP Oil Level Indicator

The Elesa+Ganter 111021-NP oil level indicator is a column-style visual monitoring component designed for hydraulic systems where clear, reliable fluid level reading is essential. Identified by the full technical code HCK.176-ZN-M12-NBR-PC-NP, this product belongs to the HCK range and is commonly used for oil and glycol-based solutions in industrial reservoirs, lubrication units, and machine hydraulic circuits.

Technical Overview

This model uses a 176 mm fixing centre distance with M12 connections, making it suitable for compact and medium-sized tanks. The “ZN” configuration refers to zinc-plated steel fixing components, while “NBR” indicates nitrile rubber sealing rings. NBR is widely preferred in oil-related applications because it offers dependable resistance to mineral oils and many standard hydraulic fluids. The “PC” reference points to a transparent polycarbonate viewing element, offering good impact resistance and easy visual inspection.

Where It Is Used

The Elesa+Ganter 111021-NP HCK.176-ZN-M12-NBR-PC-NP oil level indicator helps operators check fluid levels without opening the reservoir. This reduces contamination risk and supports preventive maintenance routines. The NP version is especially practical where a simple, direct level reading is required and the installation area is not exposed to frequent mechanical impact.

Why It Matters in Hydraulic Systems

Low oil level can cause pump cavitation, overheating, poor lubrication, and premature component wear. A visible oil level indicator gives maintenance teams a quick reference point during inspections. Its contrast screen improves readability, while the column layout allows the fluid level to be seen clearly from different angles.
