APG’s tubular gauge glass, manufactured by Duran® a division of SCHOTT AG. Our Pyrex® line, a Corning Brand, is offered in red-line, standard, heavy wall, high pressure, and heavy wall red line configurations. Pressure ratings range from 90 PSI to 600 PSI depending on the end finish, diameter and length required. APG’s tubular gage glass has outstanding resistance in chemical applications.
Our tubular glass comes in a variety of shapes and sizes. For your more economical and low-pressure applications, we would recommend our standard gauge glass. If you are looking for something that is reliable with a long service life for low-pressure water or gas flow, then our heavy wall gauge glass would be perfect for you.
Whether you are looking for glass that can be used for scientific laboratory applications or needing to read quicker and more accurate liquid level readings, APG has you covered with our heavy wall tubing and standard red line gauge glass.
