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 liquid level gauge glass is also available with red and white meniscus enhancing lines.
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.
