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

The Elesa+Ganter 111011 oil level indicator, also known as HCK.127-ZN-M12-NBR-PC-P, is a column-style fluid level indicator for hydraulic systems, oil tanks and industrial machine reservoirs. It offers a 127 mm hole centre distance, M12 connection, NBR sealing and a transparent polycarbonate tube for oil monitoring.

Technical Features

This version uses zinc-plated steel screws, nuts and washers, indicated by the ZN code. The NBR O-ring is suitable for standard oil applications with a maximum continuous working temperature of 100°C. The PC tube is intended for oil use and is paired with a removable transparent polycarbonate front protection, helping protect the indicator during everyday operation.

Visibility and Maintenance Value

The HCK.127 format provides a larger visible level range than the 76 mm version, making it useful for medium-sized tanks and reservoirs. Clear side visibility helps maintenance teams check oil level quickly, even when equipment is installed in tight or partially obstructed areas. This supports faster inspections and better preventive maintenance routines.

Common Use Cases

The Elesa+Ganter 111011 HCK oil level indicator is commonly specified for hydraulic power units, industrial presses, lubrication reservoirs, machine tools and production equipment. It is especially relevant where oil level monitoring must be simple, direct and reliable without adding electronic sensing equipment.
