Pressure gauges are protected from steam condensation in a regular boiler by using a siphon where steam condenses and prevents steam from going further up to the gauge.

However in a vacuum steam boiler when the boiler is re pressurized after use the pressure would push the water in the siphon up to the vacuum gauge.

I currently dont use any siphon and my vacuum gauges are far off (from condensation I guess) after a few boils, how can I prevent that ?

Have you tried a gauge guard? It's a simple diaphragm that allows pressure to transmit, without the liquid crossing the barrier.
