Elesa+Ganter 113131-NP Oil Level Indicator for Compact Hydraulic Reservoirs
Elesa+Ganter 113131-NP oil level indicator, coded as HCK.127-ZN-M12-FKM-PC-NP, is a compact HCK series column level indicator developed for visual oil level monitoring in hydraulic and lubrication systems.
Product Definition
This model uses the HCK.127 format, meaning it has a 127 mm hole-centre distance. It is designed for applications where operators need a clear visual indication of the oil level without adding electrical contacts, wiring or control-panel integration. The M12 mounting thread supports practical installation in many industrial tank designs.
Technical Features
The assembly ends are made from glass-fibre reinforced polyamide based technopolymer, while the support is natural aluminium. A white lacquered aluminium contrast screen improves visibility behind the transparent tube, making the oil level easier to read during maintenance rounds. The PC tube is transparent polycarbonate and is intended for oil service.
The FKM O-ring sealing system is a key technical advantage. FKM provides higher temperature resistance than standard NBR sealing in the HCK family, supporting demanding oil environments where heat may be part of normal operation. The ZN configuration includes zinc-plated steel fastening elements.
Elesa+Ganter 113131-NP Oil Level Indicator What Does NP Mean?
The NP designation means this version is supplied without the removable front protection. This can be useful where the installation area is protected, where space is limited, or where direct access to the level tube is preferred. It still provides the core visual level monitoring function expected from an HCK.127 oil level indicator.
Typical Uses
This product type is commonly used on hydraulic reservoirs, lubrication tanks, compact power units, industrial presses, machine tools and production equipment. It supports simple inspection routines by giving technicians a direct view of the oil level. In many facilities, this kind of component plays a small but important role in reducing preventable downtime.

Frequently Asked Questions
What is Elesa+Ganter 113131-NP oil level indicator used for?
It is used for visual oil level checking in hydraulic tanks, lubrication reservoirs and industrial machinery.
Does the NP version have front protection?
No. NP indicates that this version does not include the removable polycarbonate front protection.
Is this an electrical level indicator?
No. This model is a visual oil level indicator and does not include a minimum-level electrical sensor.
Why is FKM sealing important?
FKM sealing supports higher temperature resistance, making the indicator suitable for oil applications where operating heat is a relevant factor.
Where is the 127 mm version most useful?
The 127 mm version is useful on compact reservoirs where a readable level indicator is needed without requiring a long mounting footprint.
