Tubular Sight Glasses are widely used in industrial pipelines and process equipment to visually monitor the flow, level, clarity, and color of liquids. These units consist of a transparent glass tube—typically made from high-quality borosilicate glass—secured between metal end fittings and protected by a sturdy frame or guard rods. Tubular sight glasses provide continuous visual inspection of fluids without interrupting the process, making them ideal for applications where real-time monitoring is essential. Designed for durability and safety, tubular sight glasses are suitable for a wide range of industrial environments including chemical processing, oil & gas, pharmaceuticals, food processing, power plants, and water treatment systems.
Tubular Sight Glass assemblies typically include a clear borosilicate glass tube mounted between two metal end connections with sealing gaskets and protective guards. The transparent tube allows operators to directly observe liquid movement, flow condition, or fluid level inside pipelines or tanks.
The design enables easy installation, maintenance, and replacement of glass tubes when required. Optional protection shields and illumination arrangements can also be incorporated for enhanced visibility and safety.
