Elesa+Ganter 10901 HCFE.15-1/2 Oil Level Sight Glass

The Elesa+Ganter 10901 HCFE.15-1/2 oil level sight glass is a practical inspection component made for reservoirs and machine bodies where liquid level has to be checked quickly and reliably. In industrial maintenance, visual level control is often the first step in spotting lubrication loss, leakage trends, or service needs before they turn into larger operational issues.

Clear Visual Monitoring for Everyday Industrial Use

One reason the HCFE series is widely used is its straightforward function. Instead of relying on complex instrumentation for simple level confirmation, a sight glass gives maintenance staff immediate visual access to the condition inside a tank or housing. This is especially helpful on compact machinery, enclosed transmissions, and lubrication systems where space is limited and service speed matters.

The Elesa+Ganter 10901 HCFE.15-1/2 oil level sight glass is built in transparent polyamide-based technopolymer and uses an NBR synthetic rubber packing ring. The transparent body allows fast inspection, while the sealing ring helps maintain correct installation and leak-resistant performance when tightened properly.

Technical Details

This model is configured with a G 1/2 thread. The technical table lists B = 10.5, D = 16, d = 26, s = 19, and a recommended tightening torque of 4 to 6 Nm. These values matter when matching the sight glass to the available threaded port, surrounding tool clearance, and expected sealing requirements.

The component is suited to machine builders and maintenance teams that need a compact and dependable oil inspection point. Because it is a direct-reading component, it supports quicker daily checks and can simplify routine service planning. That can be valuable in production systems where visual control is preferred over more expensive monitoring solutions.

Typical Applications

This sight glass is commonly used on gearboxes, oil reservoirs, lubricated machine housings, pump systems, and compact hydraulic assemblies. The G 1/2 thread format makes it relevant in designs that use BSP-style threaded connections rather than metric threads. In retrofit work as well as original equipment manufacturing, that compatibility can make part selection much easier.

Its value is not just in showing the fluid level. It also helps standardize inspection points across equipment, which is useful when multiple machines must be checked by the same service team.

Elesa+Ganter 10901 HCFE.15-1/2 FAQ

What is the purpose of the Elesa+Ganter 10901 HCFE.15-1/2 oil level sight glass?

Its purpose is to provide a simple visual indication of oil or liquid level in a machine housing or reservoir. This helps operators verify whether the system remains within the expected working range.

Elesa+Ganter 10901 HCFE.15-1/2 Why is a G 1/2 thread important?

The thread standard defines how the part fits into the equipment. A G 1/2 thread is commonly used in many industrial systems, so selecting this version can be essential for correct installation without adapters.

How important is the tightening torque?

It is very important. The recommended 4 to 6 Nm range helps keep the sealing ring correctly positioned and supports reliable tightness during operation.

Is this a good option for routine maintenance checks?

Yes. It is especially useful where quick visual checks are part of standard maintenance practice. That makes it a practical choice for plants that want faster inspections and clearer service routines.
