All residential low pressure (15 psi) steam heating boilers, by law, must have a pressure gauge that reads 2x the maximum working pressure, or put another way, 30 psi.
The delicate watchmaker internal parts of these gauges, including the Bourdon tube, should properly be protected by a steam siphon or "pigtail".
Many steam syphons are readily apparent, but some are hidden or "internal" within the gauge mechanism itself.
