Elesa+Ganter 111046 HCK.381-SST316-M12-FKM-GL-P Oil Level Indicator

Technical Overview

The Elesa+Ganter 111046 HCK.381-SST316-M12-FKM-GL-P oil level indicator is designed for reliable visual monitoring of fluid levels in hydraulic systems, lubrication units, reservoirs and industrial equipment where clear level reading is essential. This model belongs to the HCK series and combines a 381 mm hole centre distance with M12 fixing threads, making it suitable for medium-sized tanks and machine assemblies that require a robust, readable and service-friendly level indicator.

Its GL configuration uses a transparent borosilicate glass tubular window, developed for use with oil, water and water/glycol-based solutions. The front polycarbonate protection helps shield the glass tube while remaining removable for cleaning. This makes the indicator practical in environments where dust, oil mist or process residue may affect visibility over time.

Elesa+Ganter 111046 HCK.381 Materials and Application Benefits

The SST316 specification indicates AISI 316 stainless steel hardware, a strong advantage in demanding industrial environments where corrosion resistance matters. The FKM sealing rings, commonly associated with Viton-type performance, support higher temperature resistance compared with standard NBR seals. For applications involving elevated temperatures, oils or glycol-based fluids, this configuration provides a dependable balance of visibility, mechanical strength and chemical compatibility.

The Elesa+Ganter 111046 oil level indicator is not simply a viewing accessory; it supports preventive maintenance. Operators can quickly confirm oil level status from the side, reducing inspection time and helping identify abnormal consumption, leaks or filling errors before they become operational issues.

Where It Is Commonly Used

This product type is commonly selected for hydraulic power packs, industrial gearboxes, lubrication reservoirs, cooling circuits and machinery where stainless steel fastening components are preferred. The 381 mm size provides a generous visual range without occupying excessive panel space.

Elesa+Ganter 111046 HCK.381 FAQ

What is Elesa+Ganter 111046 used for?

It is used to monitor oil, water or water/glycol-based fluid levels in reservoirs and hydraulic systems through a protected transparent tube.

What does GL mean in this model?

GL refers to the borosilicate glass tubular window, suitable for oil, water and water/glycol-based solutions.

Why is AISI 316 stainless steel important?

AISI 316 stainless steel offers improved corrosion resistance, especially in industrial environments exposed to moisture, cleaning agents or demanding operating conditions.

Is this model suitable for high-temperature applications?

The FKM sealing configuration is intended for higher temperature resistance than standard NBR versions, but final suitability should always be checked against the real fluid, pressure and temperature conditions.

Can the front protection be cleaned?

Yes. The polycarbonate front protection is removable, allowing easier cleaning when visibility is reduced by dirt or residue.
