Pressure-Rated Borosilicate Glass Tubes

Color: Clear
Max. Temperature: See table
Fabrication: Annealed

These short glass tubes can be used as glass bowls in oil dispensers. Borosilicate glass resists clouding and pitting and is highly chemical resistant. With a low rate of thermal expansion, it stays dimensionally stable during changes in temperature.

Borosilicate Glass Tubes

Color: Clear
Max. Temperature: 445° F
Fabrication: Annealed

Also called Pyrex and Schott glass, this glass resists clouding and pitting and is highly chemical and heat resistant. With a low rate of thermal expansion, it stays dimensionally stable during changes in temperature.

Ultra-High-Temperature Quartz Glass Tubes

Color: Clear
Max. Temperature: 2000° F
Fabrication: Annealed

Blistering temperatures won’t melt these quartz tubes, and rapid temperature shifts won’t cause them to crack. Even tougher than borosilicate, they can be used in furnaces and ovens heated up to 2000° F. These highly pure tubes are often used in laboratories because they won’t leach impurities into samples or contaminate chemical reactions. Quartz tubes are optically clear and have excellent UV transmission, making them ideal for UV purification systems.

Tubular Gauge Glass

Glass

Glass with a Red Line

Replace existing gauge glass or combine with valves and guard rods to build your own level indicator. Cut to size with a glass tube cutter (not included).

Glass with a red line emphasizes the liquid level so it’s easier to read.
