Main Features
1. 3/4 BSP Threaded Connection
These oil level sight glasses are designed with a 3/4 BSP threaded connection for compatible equipment. This makes them useful for replacing worn fittings or adding liquid level monitoring to suitable air compressor systems.
Important: BSP threads are not automatically compatible with NPT threads. Verify the exact thread standard, diameter, and fitting type before installation.
2. Aluminum Alloy Construction
The aluminum alloy body offers a lightweight metal construction suitable for many equipment and piping applications. It is designed to provide a practical housing for the sight glass while keeping the fitting relatively compact.
Actual corrosion resistance and durability depend on the alloy, finish, and operating environment.
3. Visual Oil Level Monitoring
The sight glass allows users to inspect the oil level through a transparent viewing area. This can make routine maintenance easier by helping you check whether the oil level appears appropriate without dismantling the equipment.
Always follow the compressor manufacturer's recommended oil level and inspection procedure.
4. Versatile Liquid Level Connector
Although primarily intended for air compressor pump oil level monitoring, the product is also listed for piping systems and storage tanks. Its usefulness in these applications depends on compatibility with the liquid, pressure, temperature, and mounting arrangement.
5. Four-Piece Replacement Set
The 4-piece package provides multiple fittings for equipment maintenance, replacement needs, or compatible installation projects. Having spare connectors available can be convenient for workshops and DIY repair tasks.
The set quantity does not necessarily mean all four fittings can be installed on one compressor.
