Hex-Duty Sight Glass – Tough Under Pressure

The Hex-Duty Oil Sight Glass (OSG) improves oil monitoring under pressure through several key design features:

High Pressure Tolerance: The Hex-Duty OSG is specifically engineered for high-stress environments, featuring a pressure rating of up to 400 psi
This is double the pressure rating of standard models, making it suitable for demanding systems like gearboxes, pumps, and storage tanks.

Enhanced Visual Clarity:
Its clear cast acrylic body allows for the immediate visual inspection of oil clarity, water contamination, and trapped sediment at a glance. By mounting the OSG at the lowest point of a reservoir, water and heavy particles naturally settle into the glass for easy monitoring

Maintenance Without Disassembly:
To manage contaminants while the system is operational, the device includes a spring-loaded drain valve. This allows operators to purge accumulated water and debris without having to disassemble the system, which reduces risk and saves time in industrial settings.

Simplified Handling:
The unique hexagonal body design provides a better grip for tools. This makes installation, disassembly, and routine maintenance quicker and safer, particularly in the tight or awkward spaces common in heavy industry applications.

To install the Hex-Duty OSG on side-mounted ports, you should use an elbow adaptor.

This configuration ensures the sight glass is positioned so that water and heavier particles can naturally settle into the glass for inspection and removal.

In general, the OSG is intended to be mounted at the lowest point of a reservoir. The hexagonal body design of the device is specifically engineered to provide a better grip for tools, making the installation process quicker and safer, particularly when dealing with tight or awkward spaces.

The Hex-Duty Oil Sight Glass (OSG) is specifically designed for **high-stress environments** and is best suited for the following types of equipment:

* **Pumps**
* **Gearboxes**
* **Storage tanks**
* **Most oil-lubricated machinery**

This sight glass is a valuable addition to lubrication strategies within **heavy industry, manufacturing, power generation, and marine sectors**. Its high pressure rating of **up to 400 psi**-which is double that of standard models-makes it particularly ideal for demanding systems where reliable performance under pressure is critical.
