Elesa+Ganter 111034 HCK.254-ZN-M12-NBR-GL-P Oil Level Indicator

The Elesa+Ganter 111034 HCK.254-ZN-M12-NBR-GL-P oil level indicator is a 254 mm column level indicator built with a borosilicate glass transparent tube. It is designed for visual fluid level monitoring in oil systems and, depending on operating conditions, water or water-glycol based solutions. This makes it a flexible option for hydraulic, lubrication and industrial reservoir applications.

Technical Overview

This version uses zinc-plated steel screws, nuts and washers, an NBR sealing ring, a GL borosilicate glass tube and transparent front protection. Its HCK.254 size provides a 254 mm fixing hole centre distance, M12 thread, 291 mm overall length and 198 mm visible level area. The front protection helps reduce exposure of the glass tube to direct contact during operation.

Why Borosilicate Glass Matters

The GL execution is important when fluid compatibility is a key selection factor. Compared with a standard PC tube, borosilicate glass is often preferred for broader fluid visibility requirements, especially where oil, water or water-glycol solutions may be present. For real operating conditions, compatibility should always be checked against temperature, pressure and fluid type.

Industrial Use Cases

This indicator can be found in hydraulic power packs, machine reservoirs, cooling-lubrication units, industrial presses and process equipment where technicians need dependable visual level control. A readable level indicator supports faster inspection rounds and helps reduce the risk of running equipment below recommended fluid levels.
