Elesa+Ganter 111031 HCK.254-ZN-M12-NBR-PC-P Oil Level Indicator

The Elesa+Ganter 111031 HCK.254-ZN-M12-NBR-PC-P oil level indicator is designed for clear visual monitoring of fluid levels in hydraulic tanks, lubrication systems, reservoirs and industrial equipment where reliable level reading matters. With a 254 mm hole centre distance, M12 fixing thread and a transparent polycarbonate tube, this model gives operators a practical way to check oil level without opening the tank or interrupting the system.

Technical Overview

This HCK.254 version uses zinc-plated steel screws, nuts and washers, an NBR synthetic rubber sealing ring, a polycarbonate transparent level tube and a removable polycarbonate front protection. The PC tube is intended for oil applications, while the front protection helps shield the viewing area during daily operation and can be removed for cleaning. Its 291 mm overall length and 198 mm visible level area make it suitable for medium-sized tanks that require quick inspection from the front or side.

Where It Is Commonly Used

Oil level indicators like this are widely used in hydraulic power units, machine tools, gearboxes, mobile equipment, industrial presses and lubrication reservoirs. In these environments, a visible level gauge can support preventive maintenance by helping teams spot low oil levels, contamination symptoms or irregular consumption before they become operational issues.

Why Material Selection Matters

The zinc-plated steel hardware provides a standard mechanical fixing solution for general industrial environments. The NBR O-ring is commonly selected for oil service and continuous working conditions up to the manufacturer’s stated range. For equipment exposed to aggressive fluids, higher temperatures or outdoor corrosion risk, alternative versions with FKM or stainless steel hardware may be more suitable.

It is used to visually monitor oil level in hydraulic tanks and industrial reservoirs without opening the system.

Is this model suitable for water-glycol fluids?

This specific PC version is mainly intended for oil. For water or water-glycol solutions, a GL borosilicate glass version is generally more appropriate.

What does the “P” at the end of the code mean?

“P” indicates that the indicator includes transparent front protection made of polycarbonate.

What does “ZN” mean in this product code?

“ZN” refers to zinc-plated steel screws, nuts and washers.

Why choose a 254 mm oil level indicator?

A 254 mm centre distance offers a longer visible range than compact indicators, making it useful for medium reservoirs where a broader level reading is needed.
