Plain Gauge Glass Level Tubes

Plain gauge glass tubes are an essential component in steam boiler and water level gauge assemblies, providing a clear and reliable visual indication of water level in boilers, pressure vessels, and associated plant. Manufactured from high-quality borosilicate glass to withstand the demands of high-temperature and high-pressure steam applications, these tubes offer excellent clarity and durability in service.

Available in a comprehensive range of lengths and outside diameters to suit the majority of standard water level gauge fittings, each tube is supplied ready to fit. Sizes are available in both imperial and metric dimensions, with outside diameters of 1/2", 5/8" and 3/4" across lengths from 7" up to 2 metres, ensuring a suitable replacement can be found for virtually any gauge assembly.
