Tubular Sight Glass

The best tubular sight glass supplier for your complex observation needs

Superior-quality tubes are not something you can overlook for technical observation purposes. To never have to worry about production and resistance, explore a range of tubing and packing sleeves from Ovictor Glass. Our glass sight glass tubes are ideal for applications where high temperatures and corrosive chemicals are involved.

Our heavy-duty tubes are manufactured using carefully selected raw materials to not crack under pressure or temperature swings. From now on, you can observe your flows in real time without stopping operations. 

Gauge tube manufacturer that achieves premium quality every time

Are you into checking the level of liquids in a massive storage tank? No problem. Our tubing can be made in large diameters. Do you need to monitor flows in a narrow pipe? Smaller sizes are also available. Our cheap tubular gauge glasses for sale let you have an optimal viewport for your specific setup, regardless of its dimensions.

Choose what works best for your operating environment and safety requirements.

Borosilicate tubing

Made of heat-resistant borosilicate glass, tubular pieces can cope with temperatures up to 500°C for short periods. You can order these gauge glass tubes online to monitor chemicals, petroleum products, and steam without worrying about the piece cracking or clouding. These products won’t corrode or weaken when exposed to caustic or acidic fluids. What’s more, you can upgrade to redline and multicolor alternatives if your liquid is colorless and the transparency of the tube makes it difficult to see what’s happening to it.

Quartz tubing

When you purchase a tubular glass gauge engineered from quartz, you know it can resist extremely high heat without softening or melting – up to 1450 °C (short-term temperatures) and up to 1100°C (continuous use). This makes quartz perfect for environments where other materials can’t endure temperatures, including in furnaces and reactors. The clarity of quartz also allows for spectroscopic analysis and optical measurements.

Soda lime options

If temperature fluctuations are not a concern at your facility, buy a gauge glass tube made of soda lime. While having a maximum working temperature of 150°C, soda lime pieces work well with corrosive materials. These tubes are highly resistant to acids and solvents and stand up well to saline solutions. They maintain strength and transparency, whether used in medical devices, laboratory equipment, or industrial processes.
