Gauge glass – full assembly
The gauge glass is also available as glass alone – the pictured item is the full assembly.
The assembly comes complete with valves and unions on both ends, and provides prototype blow-down operation.
The assembly measures approximately 5-1/2 between union ends.
The bottom end requires a 1/8″ pipe threaded hole in the backhead. Thereafter, when removing for service, loosen the two unions and the whole assembly comes off.
Glass size is 1/2″ OD.
