Gauge Glass

Gauge Glass

Gauge Glass is commonly changed out at service intervals on boilers. This is particularly the case for Borosilicate Gauge Glass which forms the clear round level gauge you can view the Water / Steam level on a boiler. This will degrade at different rates depending upon the water quality of the boiler, but it is most often changed out at quarterly services regardless of the condition. Hawleys has this glass available in 3.2mm and 5.5mm wall thicknesses and in any length under 1500mm. Quite often a service technician will hold a few full lengths (1500mm) of this glass on them and cut it to size at the time of the service. Hawleys also has spare Reflex and Transparent Gauge Glass available.
