Tubular Gauge Glasses | Industrial

We manufacture a wide range of tubular gauge glass types and sizes for sight level work in applications ranging from coffee machines to industrial steam boilers. They are manufactured from low expansion Borosilicate glass, specially noted for its high chemical and corrosion resistance, and its clarity and mechanical strength

All standard diameters are stocked, including 3/8", 7/16" 1/2", 9/16", 5/8", 11/16", 3/4", 7/8" and 1". We can also produce glass to meet specific customer requirements. Standard lengths are up to 2 metres and longer lengths of some diameters can be supplied on special request

Glasses can be supplied with ends cut or flame polished. It is assumed that lengths of 48" and under are to be used as finished gauge glasses and are therefore supplied with flame polished ends

Standard Type

Glasses made from borosilicate tubing are used for low pressure applications, such as level indication in tanks etc, where hydrostatic pressure is the only consideration

Available from stock in 5/8” diameter. Other sizes are available on special request

High Pressure Type

These glasses are manufactured from our high quality borosilicate tubing and are especially suited for heavy duty sight level work in a range of pressure applications such as boilers, tanks and pressure vessels. This type of gauge glass is also available with red and white meniscus enhancing lines

Heavy Wall Type

This extra heavy walled tubing allows even higher pressure ratings (up to 600psi) than the high pressure type. It is available in 5/8” and 3/4” diameters in lengths up to 48”

As with the high pressure glass, this type is also available with red and white meniscus enhancing lines

Red-line Type

This type of gauge glass has red and white meniscus enhancing lines. This is achieved by the application of specially developed paints that are bonded to the glass without etching. The use of low curing temperatures means no pressure rating reduction is necessary
