Tubular Gauges

Tubular gauges, also called gauge glasses or sight glasses, give a direct visual reading of liquid level in boilers, tanks and pressure vessels. They're simple and reliable, and they don't need power.

Tubular Gauge Components

• Gauge glasses – borosilicate tubes in standard lengths and diameters
• Gauge valves – isolate the glass for safe replacement
• Protector rods and guards – shield glass from impact
• Packing and washers – leak-free sealing
• Ball check valves – stop flow if the glass breaks

Safety & Maintenance

Select glass rated for your pressure and temperature, and always use guards on pressurized vessels. Replace glass that shows etching, cloudiness or chips. Blow down gauges regularly on boilers to confirm accurate readings and clear sediment.
