DURAN® HEAVY WALL REDLINE TUBULAR GAUGE GLASS
WE CUT TO ANY LENGTH!
Why Redline?
Redline striped glass makes clear liquids such as water very easy to see compared to clear glass tubes, especially when viewing from a distance. By positioning the redline stripe opposite or away from the operator’s viewing position, the redline stripe is magnified by the water in front of it. In the tube where the clear liquid is present, the red stripe appears much wider compared to where there is no liquid.
Features
- Heavy Wall Redline tubular glass for high pressure and steam applications
- Best gauge glass for saturated steam/water applications
- High Quality Borosilicate Duran® glass manufactured by Schott North America, Inc.

Application Notes
- Steam Service: Limited to 24” Lengths
- Vacuum Service: Acceptable with properly designed valves and seals
- Compatibility: Before ordering, verify that all the materials of construction, pressures, temperatures, and any other specifications are compatible with the design, media(s), cleaning solutions, and the environment of the application and future applications. The John C. Ernst Co. does not make compatibility recommendations. Compatibility determinations, corrosion or otherwise, are the responsibility of the user.
Some medias reduce the useful life of gauge glass by chemical action, such as Hydrofluoric Acid (HF), hot concentrated Phosphoric Acid (H3PO4), Sodium Hydroxide (NaOH) and Potassium Hydroxide (KOH) above 125°F, steam or superheated water above 250°F. Alkaline solutions attach glass very slowly at room temperatures, but as temperature is increased over 100°F, the corrosion rate rises rapidly. Steam can etch or corrode glass thus weaken the glass tube.
